Every Fish Pokemon Guide

The Pokédex is filled with many fish Pokémon. Of all the living creatures that have been used as Pokemon inspiration, fish are the most used concept.

These Pokémon are very characteristic, and most of them are widely known by Pokéfans and people outside the franchise, like Magikarp or Goldeen! So, the Pokéfishes are very important, and I want to show you the greatness of these under-appreciated beasts.

What Will You See In This Guide? 

I can best show you the awesomeness of these Pokémon by asking you to picture this guide as if you are seeing a big aquarium filled with all the Pokéfishes you can imagine. In this aquarium, you’ll see big sharks, enormous sea serpents, cute manta rays, and more! Thanks to our great aquarium, we can study the behavior, biology, and the most interesting features and facts of these Pokéfishes! 

Also, you’ll find some special Pokéfishes which are very strong; they can be used for competitive matches, and I’ll teach you how to use them properly! We have plenty of Pokémon to see, so let’s get started!

Horsea, Seadra & Kingdra

The first fish Pokémon to appear on the National Dex is Horsea and its evolutions, Seadra and Kingdra. And yes, the Seahorses are considered fish! 

Horsea 

• National Dex Number: 116
• Category: Dragon Pokémon
• Type: Water-type

Where to Find Horsea?

You’ll have to fish with a Good or a Super Rod in the following places if you want to find Horsea: 

• Red & Blue: Routes 19, 20, and 21, Seafoam Islands, and Cinnabar Island. 
• Yellow: You’ll find our little seahorse friend on Yellow by fishing on Routes 10, 11, 12, and 13 and Vermillion City. 
• Gold, Silver, Crystal, HeartGold & SoulSilver: Whirl Islands. 
• Ruby, Sapphire, and Emerald: Routes 132, 133, and 134. 
• FireRed and LeafGreen: Vermillion City, Pallet Town, and Cinnabar Islands and in the vast majority of the Sevii Islands. Places like Bond Bridge, Treasure Beach, Tanoby Ruins, Water Labyrinth, and Water Path are filled with Horseas. You’ll also find it on Routes 4, 10, 11, 12, 13, 19, 20, 21, and 24. 
• Diamond, Pearl & Platinum, Brilliant Diamond & Shining Pearl: Route 226. 
• Black, White, Black 2 & White 2: Routes 17 and 18, and in P2 Laboratory roundabouts.
• X & Y: Ambrette Town and Cyllage City. 
• Omega Ruby & Alpha Sapphire: Routes 130, 131, 132, 133, and 134 and the Sealed Chamber. 
• Sun, Moon, Ultra Sun, & Ultra Moon: You’ll find Horsea using the Island Scan on Kala’e Bay, but only on Wednesdays. 
• Sword and Shield: Horsea is only obtainable after getting the first Expansion Pass, and it’ll appear in the Insular Sea. 

Seadra 

• National Dex Number: 117
• Category: Dragon Pokémon
• Type: Water-type

When Horsea reaches Level 32, it’ll evolve into Seadra. There’s not much to say about Seadra, so let’s take a look at its final evolution. 

Kingdra 

• National Dex Number: 230
• Category: Dragon Pokémon
• Type: Water/Dragon-type

When Seadra gets traded while holding a Dragon Scale, it’ll evolve into Kingdra. 

Battle Usage; Sweeper Kingdra 

Kingdra is not the strongest Pokémon; all of its stats are pretty even except for its HP, which is below average. Likewise, it isn’t the fastest Pokémon. Still, it’s a great option in low-end competitive tiers, like NU or RU, because of its strength and type combination. 

In fact, Kingdra is mostly used in Double Battles or on Rain-based teams thanks to its ability, Swift Swim. Let’s see its most-famous strategy: 

• Surf
• Ice Beam
• Draco Meteor or Dragon Pulse
• Hurricane

With Life Orb as its item, Swift Swim as its ability, and Modest as its Nature. 

• EVs: 252 SpA / 252 Spe / 4 Def

The idea behind this build is to have a Rain Setter in the team, who will be responsible for setting the rain whenever it stops. Any Pokémon with Drizzle as its ability can perform this role perfectly. 

As the rain is set, Kingdra can get on the field and start landing Hurricanes, destroying the enemy team entirely. 

Goldeen & Seaking

Goldeen 

• National Dex Number: 118
• Category: Goldfish Pokémon
• Type: Water-type

I’m sure Goldeen comes to mind when people think about Fish Pokémon, and it’s not a coincidence. Remember Misty’s Goldeen and its constant, weirdly humanized, and a bit unsettling “Goldeen, Goldeen?”

Where to Find Goldeen? 

You’ll find Goldeen by fishing or surfing in the following places: 

• Red, Blue, & Yellow: Routes 6, 10 to 13, and 17 to 25. You’ll also find it in any City with access to a water lake or river, including the Safari Zone, Seafoam Islands, Cinnabar Island, Indigo Plateau, and the Cerulean Cave. 
• Gold, Silver, Crystal, HeartGold, & SoulSilver: Routes 4, 9, 10, 24, 25, and 42, Dark Cave, Union Cave, and the Slowpoke Well. You’ll also find it if you surf in Cerulean City, Mt. Silver, or Tohjo Falls.
• Ruby, Sapphire, & Emerald: Routes 102, 111, 114, 117, and 120. Also, it’ll appear on Petalburg City, Meteor Falls, Safari Zone, and Victory Road. 
• FireRed & LeafGreen: Routes 6, 22, 23, and 25. You’ll also find it on Ruin Valley, Cape Brink, Four Island, Icefall Cave, Viridian City, and the Cerulean Cave. 
• Diamond, Pearl & Platinum, Brilliant Diamond & Shining Pearl: Routes 203, 204, 209, 212, and 214, any of the three Lakes, Twinleaf Town and Sendoff Spring. 
• Black, White, Black 2 & White 2: Routes 3, 11, and 14, Striaton City, Lostlorn Forest, and the Abundant Shrine. In Black 2 & White 2, It also appears on Aspertia City! 
• X & Y: Routes 3 and 22. 
• Omega Ruby & Alpha Sapphire: Routes 102, 111, 114, 117, 120, and 123, Petalburg City, Meteor Falls, Scorched Slab, and Victory Road. 
• Sun, Moon, Ultra Sun, & Ultra Moon: Brooklet Hill. 
• Sword and Shield: Routes 4, 5, 6, East and West Lake Axwell, North and South Lake Miloch, Bridge Field, and Giant’s Cap. 

Seaking 

• National Dex Number: 119
• Category: Goldfish Pokémon
• Type: Water-type

When Goldeen gets to Level 33, it’ll evolve into Seaking. 

Battle Usage 

Seaking is not a common Pokémon in the competitive meta. Therefore, I don’t recommend using it; there are way better options than this Pokémon. 

Nonetheless, Seaking is the perfect Pokémon for adventures; it’s strong enough to do it perfectly against the Gym Leaders and can learn Surf and Waterfall. If you didn’t choose the Water-type starter on your adventure, Seaking could fulfill that role without problems! 

Magikarp & Gyarados

Magikarp 

• National Dex Number: 129
• Category: Fish Pokémon
• Type: Water-type

Even people who don’t know Pokemon know Magikarp and remember it for being useless. Nonetheless, I love what the anime did to Magikarp, giving it a cult status as one of the Pokémon with the highest jump ever. There are even some Magitournaments where a lot of Magikarps from several Magitrainers test their Magiabilities in the Magikarp High Jump Competition. Branding is getting Magi-aggressive these days. 

Where to Find Magikarp? 

You’ll find Magikarp when fishing with the Old Rod, no matter where you fish. So, trust me, look for a water body and use the Old Rod; Magikarp will magically appear! 

Gyarados 

• National Dex Number: 130
• Category: Atrocious Pokémon
• Type: Water/Flying-type

When you train a Magikarp enough to get to Level 20, it’ll evolve into Gyarados. 

Battle Usage, Sweeper Gyarados 

We have to give usage to that Gyarados’ aggression, right?  Gyarados is a good competitive Pokémon that is constantly used in mid-tier elo’s, like UU. It also has some stellar appearances on OU. It’s a reliable Water-type Sweeper, and it works with the following build: 

• Dragon Dance
• Waterfall 
• Earthquake
• Any other offensive move, depending on your team’s flaws. 

With Heavy-Duty Boots as its item, Moxie as its ability, and Adamant as its Nature. 

• EVs: 252 Atk / 252 Spe / 4 Def

The idea with Gyarados is to get on the field and, if it has a chance on the first turn, start using Dragon Dance.  Now that it’s faster than its opponents, it can use Waterfall as its strongest Water-type move while having Earthquake to defend itself from the dangerous Electric-type users. 

I usually reserve the last move slot for Ice Fang, as it works like a charm on many strong Pokemon, like Salamence or Dragonite, but you can also opt for Crunch. As I said, it will depend on your team’s needs. I choose Heavy-Duty Boots for Gyarados because it’s especially sensitive to Rock-type moves. 

Chinchou & Lanturn

Chinchou 

• National Dex Number: 170
• Category: Angler Pokémon
• Type: Water/Electric-type

Where to Find Chinchou? 

To get Chinchou, you’ll have to fish with a Good or a Super Rod in the following places: 

• Gold, Silver, Crystal, HeartGold, & SoulSilver: Routes 20, 21, 26, 27, and 41, New Bark Town, Pallet Town, Vermillion City, and Cinnabar Island. 
• Ruby, Sapphire, & Emerald: You’ll only find Chinchou by going underwater on Routes 124 and 126. 
• Diamond, Pearl & Platinum, Brilliant Diamond & Shining Pearl: Route 220. 
• Black & White: Route 18 and Driftveil City. 
• Black 2 & White 2: Undella Bay. 
• X & Y: Azure Bay or Shalour City. 
• Omega Ruby & Alpha Sapphire: Chinchou will only appear on the underwater paths of Routes 107, 124, 126, 128, 129, and 130. 
• Sun, Moon, Ultra Sun, & Ultra Moon: Route 8 and Akala Outskirts. 
• Sword and Shield: Hulbury, Giant’s Mirror, East and West Lake Axewell.  

Lanturn 

• National Dex Number: 171
• Category: Light Pokémon
• Type: Water/Electric-type

Battle Usage; Bulky Toxic Lanturn 

One thing is sure, Lanturn is a chunky Pokémon. It has a lot of HP and a great defensive type combination, making it a reliable option to get rid of most Fire-types and Walls in low tiers, like NU or PU. It can work with the following build: 

• Volt Switch
• Toxic
• Surf or Scald
• Ice Beam

With Mystic Water as its item, Volt Absorb as its ability, and Calm as its Nature. 

• EVs: 252 SpA / 252 SpD / 4 Spe

This build is intended to make Lanturn the principal weapon against bulky Pokémon, as it’ll use Toxic to chip them down and then attack with Surf and Ice Beam. 

If Lanturn is in a sketchy situation, it can just leave the place by using Volt Switch. 

Qwilfish & Overqwil

Finally, we arrived at one of my favorite Pokémon and, sadly, one of the most forgotten ones, Qwilfish. 

Qwilfish 

• National Dex Number: 211
• Category: Balloon Pokémon
• Type: Water/Poison-type.

I’m always spreading my love for Qwilfish on social media; it deserves more than just being remembered for swallowing water! 

Where to Find Qwilfish? 

You’ll find Qwilfish by fishing with a Super Rod in the following places: 

• Gold, Silver, Crystal, HeartGold, and SoulSilver: Routes 12, 13, and 32. 
• FireRed: Five Isle Meadow, Green Path, Memorial Pillar, Outcast Island, Resort Gorgeous, Tanoby Ruins, Trainer tower, Water Labyrinth, and the Water Path. 
• Diamond, Pearl & Platinum, Brilliant Diamond & Shining Pearl: Iron Island. 
• Black & White: Route 17 and 18 and P2 Laboratory. 
• Black 2 & White 2: Route 4, Virbank City, and Virbank Complex. 
• X & Y: Route 8. 
• Sword and Shield: Route 9, Dusty Bowl, Lake of Outrage, and Bridge Field. 

Battle Usage; Offensive, Entry Hazard Setter Qwilfish 

I couldn’t help but add a build for Qwilfish as it has great usage as an Entry Hazard Setter in low-end tiers, like PU, which is the last tier of the competitive system. 

Qwilfish can work with the following build:

• Spikes
• Liquidation
• Poison Jab
• Taunt

With Black Sludge as its item, Poison Point as its ability, and Jolly as its Nature. 

• EVs: 252 HP / 252 Spe / 4 Def or Atk

Qwilfish will be the first Pokémon you use in a battle to set Spikes in the very first turn. After setting the Spikes, you can switch Qwilfish or use it to attack your opponents with Liquidation and Poison Jab. I like to use Taunt as a backup move as it will work to prevent other Entry Hazard Setters and Setup Pokémon from doing their dirty tricks. 

Hisuian Qwilfish 

• National Dex Number: 211
• Category: Balloon Pokémon
• Type: Dark/Poison-type

Where to Find Hisuian Qwilfish? 

Hisuian Qwilfish only appears in Legends: Arceus, and you’ll find it on Ramanas Islands, Tranquility Cove, Lunker’s Lair, and Islespy Shore. 

Overqwil 

• National Dex Number: 904
• Category: Pin Cluster Pokémon
• Type: Dark/Poison-type

If you make Hisuian Qwilfish use the Strong Style Barb Barrage 20 times, it’ll evolve into Overqwil. 

What Happened to Overqwil? 

To make Qwilfish evolve into Overqwil, it needed to use a move that doesn’t exist in the modern Pokémon world. Also, Qwilfish has to use a specific technique discarded over time to evolve. 

With Hisuian Qwilfish hiding from humans and only a few humans knowing its evolving method, it was only a matter of time before Qwilfish’s evolving method was forgotten.

Remoraid & Octillery

Remoraid 

• National Dex Number: 223
• Category: Jet Pokémon
• Type: Water-type

Where to Find Remoraid? 

To get Remoraid, you’ll have to fish with a Good or a Super Rod in the following places:

• Gold, Silver, HeartGold, and SoulSilver: Route 44.
• LeafGreen: Five Isle Meadow, Green Path, Memorial Pillar, Outcast Island, Resort Gorgeous, Tanoby Ruins, Trainer tower, Water Labyrinth, and the Water Path. 
• Diamond, Pearl & Platinum, Brilliant Diamond & Shining Pearl: Routes 213, 222, 223, 224, and 230, Pastoria City, Sunyshore City, and the Pokémon League. 
• Black & White: Undella Town. 
• Black 2 & White 2: Route 21 and the Undella Bay. 
• X & Y: Route 12, Shalour City, and Azure Bay. 
• Ultra Sun & Ultra Moon: Routes 1 and 8, Hau’oli City, Kala’e Bay, and Melemele Sea. 
• Sword and Shield: Route 9, South Lake Miloch, and West Lake Axewell. 

Octillery 

• National Dex Number: 223
• Category: Jet Pokémon
• Type: Water-type

If Remoraid trains enough to get to Level 25, it’ll evolve into Octillery. 

Why Does Remoraid Evolve Into Octillery? 

Octillery is based on cannons, as it shoots big ink projectiles. These two Pokémon maintain their main inspiration concept, but I feel this concept was poorly executed. Instead of an octopus, I would choose to make Remoraid evolve into a ship-like fish with cannons or something like that, but without making it lose its fish shape. 

Mantyke & Mantine

Our next Pokéfish is Mantine and its pre-evolution, Mantyke. It’s great to talk about it after talking about Remoraid, as they are heavily related. 

Mantyke 

• National Dex Number: 458
• Category: Kite Pokémon
• Type: Water/Flying-type.

Where to Find Mantyke? 

You’ll find Mantyke by surfing in the following places:

• Diamond, Pearl & Platinum, Brilliant Diamond & Shining Pearl: Route 223 and Sunyshore City. 
• HeartGold: The only way to get Mantyke is by breeding a Mantine while holding a Wave Incense. You’ll find Mantine by surfing on Route 41. 
• Black & White: Undella Town and Undella Bay. 
• Black 2 & White 2: Route 21 and the Undella Bay. 
• X & Y: Route 12, Shalour City, and Azure Bay. 
• Ultra Sun & Ultra Moon: Routes 1 and 8, Hau’oli City, Kala’e Bay, and Melemele Sea. 
• Sword and Shield: Route 9, Lake of Outrage, and Motostoke Riverbank. 

Mantine 

• National Dex Number: 226
• Category: Kite Pokémon
• Type: Water/Flying-type

If you level Mantyke up while having a Remoraid in your party, it’ll evolve into Mantine. Don’t worry; your appreciated Remoraid will not disappear! 

Battle Usage, Defogger Mantine 

When I said Mantine is very strong, I meant it. But that’s not all, Mantine has several utilities, like being one of the few Defog users in the low-end tiers of the competitive meta. 

People use Mantine to get rid of those Entry Hazard Setters, and it can do it well with the following build: 

• Defog
• Ice Beam
• Scald
• Air Slash

With Heavy-Duty Boots as its item, Water Absorb as its ability, and Modest or Bold as its Nature, depending on your playstyle. 

• Defensive EVs: 252 HP / 252 Def / 4 Spe
• Offensive EVs: 252 Spe / 252 SpA / 4 Def
• Balanced Evs: 252 HP / 126 SpA / 126 Def / 4 Spe

Defog is one of the best utility moves of the game. It’s quite simple; Defog removes all the Entry Hazards off the field. This move is the main counter of all the Entry Hazard Setters! As I said, Mantine is very strong. Still, its type combination makes it vulnerable to Dragon, Electric, and Ice-type Pokémon. That’s why it has Ice Beam and Air Slash as its moves; it needs to cover its flaws! 

The main issue is the Electric-type. A well-landed Thunder can leave our Mantine cooked to perfection, so I recommend having a Ground-type on your team! 

Carvanha & Sharpedo

Carvanha 

• National Dex Number: 318
• Category: Savage Pokémon
• Type: Water/Dark-type.

Where to Find Carvanha? 

To find this Pokémon, you’ll have to fish with a Good or a Super Rod in the following places: 

• Ruby, Sapphire & Emerald: Routes 118 and 119. 
• Diamond, Pearl, Platinum, Brilliant Diamond & Shining Pearl: Great Marsh.
• Black, White, Black 2 & White 2: Village Bridge.
• X & Y: Route 22. 
• Omega Ruby & Alpha Sapphire: Routes 118 and 119.
• Sun & Moon: The only way to get Carvanha in these games is by breeding Sharpedo, which can be found on the Poni Breaker Coast. 
• Ultra Sun & Ultra Moon: Poni Breaker Coast. 
• Sword and Shield: Carvanha doesn’t appear on SS until the first Expansion Pass, where you can find it on Training Lowlands. 

Sharpedo 

• National Dex Number: 319
• Category: Brutal Pokémon
• Type: Water/Dark-type.

When Carvanha trains until Level 30, it’ll evolve into Sharpedo. 

Battle Usage, Late-Game Sweeper Sharpedo 

Sharpedo can play as a Sweeper, thanks to its violent Nature. Its Attack and Special Attack are very good, as well as its Speed, but its defenses are really bad, making it a glass cannon. 

So, Sharpedo can destroy the enemy team with the following build: 

• Waterfall
• Crunch
• Poison Jab
• Rock Tomb

With Life Orb or Heavy-Duty Boots as its item, Speed Boost as its ability, and Adamant as its Nature. 

• EVs: 252 Atk / 252 Spe / 4 Def

This build is very straightforward; Waterfall and Crunch are Sharpedo’s STAB moves, while Poison Jab and Rock Tomb will allow Sharpedo to breach the defenses of Grass and Bug-type Pokémon, respectively. 

Barboach & Whiscash

Barboach 

• National Dex Number: 339
• Category: Whiskers Pokémon
• Type: Water/Ground-type.

Where to Find Barboach? 

You’ll get Barboach by fishing with a Good Rod in the following places: 

• Ruby, Sapphire & Emerald: Routes 111, 114, and 120, Meteor Falls, and Victory Road. 
• Diamond, Pearl, Brilliant Diamond & Shining Pearl: Routes 205, 208, 210, 212, 227, and 228, Celestic Town, Eterna City, Great Marsh, Mt. Coronet, Oreburgh Gate, and Ravaged Path. 
• Platinum: Routes 205, 210, 225, 227, and 228, Eterna City, Great Marsh, Mt. Coronet, Oreburgh Gate, and Ravaged Path.
• Black, White, Black 2 & White 2: Route 8, Icirrus City, and Moor of Icirrus. 
• X & Y: Route 14 and 19. 
• Omega Ruby & Alpha Sapphire: Routes 111, 114, and 120, Meteor Falls, and Victory Road. 
• Sun & Moon: The only way to get Carvanha in these games is by breeding Sharpedo, which can be found on the Poni Breaker Coast. 
• Sun, Moon, Ultra Sun & Ultra Moon: Paniola Town, Poni Gauntlet, Poni Meadow, Seaward Cave, and Vast Poni Canyon. 
• Sword and Shield: Barboach will appear as a roaming Pokémon on Stony Wilderness, while you’ll find it by fishing in Motostoke, Galar Mine No. 2, North and South Lake Miloch, and Slumbering Weald. 

Whiscash 

• National Dex Number: 340
• Category: Whiskers Pokémon
• Type: Water/Ground-type.

When Barboach hits level 30, it’ll evolve into Whiscash! 

Battle Usage

Whiscash is a great Pokémon for adventures, as it has a great type combination. It’s always great to have a Water-type Pokémon with immunity to Electric-type moves! If you want Whiscash to join your team, it’ll do it greatly alongside a Fire-type Pokémon that neutralizes its weaknesses to Ice and Grass-type moves. 

Feebas & Milotic

Feebas 

• National Dex Number: 349
• Category: Fish Pokémon
• Type: Water-type.

Where to Find Feebas? 

• Ruby, Sapphire, and Emerald: Feebas only appear on the river of Route 119 and only on six different river tiles. These tiles are random, so to get Feebas, you’ll have to fish on every tile for a while. Eventually, it’ll pop up on your screen! 
• Diamond, Pearl, Platinum, Brilliant Diamond & Shining Pearl: Feebas only appears on the second floor of Mt. Coronet. There, you’ll find a cavern lake. 

Feebas can only spawn on four different lake tiles, making the task of getting it unnecessarily hard. But that’s not all, as Feebas’ spawning tiles will change daily, so you only have 24 hours to hunt it; if you take more than that, you’ll have to start again.  

• Black, White, Black 2 & White 2: Route 1. 
• Omega Ruby & Alpha Sapphire: Route 119. 
• Sun, Moon, Ultra Sun & Ultra Moon: Brooklet Hill. 
• Sword & Shield: Route 2 or Ballimere Lake. 

Milotic 

• National Dex Number: 350
• Category: Tender Pokémon
• Type: Water-type.

If you make Feebas feel beautiful enough or trade it while holding a Prism Scale, it’ll evolve into a Milotic. 

Battle Usage 

Milotic is a great Pokémon for the post-game. Traning a Milotic to confront the Battle Frontier of Emerald or Platinum is a great idea, as it can learn Ice Beam, Surf, and many Ground-type moves, making it an option against a wide variety of Pokémon. 

Also, Milotic is bulky and will handle damage with no effort! 

Clamperl, Huntail & Gorebyss

Clamperl 

• National Dex Number: 366
• Category: Bivalve Pokémon
• Type: Water-type.

Where to Find Clamperl? 

• Ruby, Sapphire, and Emerald: To get Clamperl, you’ll have to explore the Underwater caves of Routes 124 and 126. 
• Diamond, Pearl, Brilliant Diamond & Shining Pearl: Clamperl can be found by fishing on Routes 219 and 221 with a Super Rod. 
• HeartGold & SoulSilver: Clamperl can be found by surfing on Route 19, but only during swarms. 
• Black, White, Black 2 & White 2: You’ll find it by fishing on Route 4. 
• X & Y: You’ll have to fish on Route 12. 
• Omega Ruby & Alpha Sapphire: Again, Underwater caves of Routes 107, 124, 126, 128, 129, and 130. 
• Ultra Sun & Ultra Moon: Fishing on Route 15 and Melemele Sea. 

Huntail 

• National Dex Number: 367
• Category: Deep Sea Pokémon
• Type: Water-type.

When Clamperl gets traded while having a Deep Sea Tooth, it’ll evolve into Huntail! Huntail is one of those forgotten Water-types that people don’t look for until the end of the adventure, so no one really uses it.

Gorebyss 

• National Dex Number: 368
• Category: South Sea Pokémon
• Type: Water-type.

If Clamperl gets traded while holding a Deep Sea Scale, it’ll evolve into Gorebyss! Gorebyss is a far cry from its counterpart, as it’s really useful, especially in Pokémon Contests! 

Relicanth

• National Dex Number: 369
• Category: Longevity Pokémon
• Type: Water/Rock-type.

Story 

Relicanth has the most interesting story of all the PokéFishes, as it was believed to be extinct from Sharpedos. 

Only a few Relicanths survived and they decided to move to deeper seas, where they changed their shape into the one it has right now. 

Where to Find Relicanth? 

Relicanth can be found by fishing with a Super Rod in the following places: 

• Ruby, Sapphire, and Emerald: Surfing on the Underwater of Routes 124 and 126. 
• Diamond, Pearl, Brilliant Diamond & Shining Pearl: Route 226.
• HeartGold & SoulSilver:  Route 19, but only during swarms. 
• Black, White, Black 2 & White 2: Route 4. 
• X & Y: Ambrette Town and Cyllage City. 
• Omega Ruby & Alpha Sapphire: You’ll find Relicanth by surfing on the Underwater caves of Routes 107, 124, 126, 128, 129, and 130. 
• Sun & Moon: Poni Wilds.
• Ultra Sun & Ultra Moon: Poni Breaker Coast. 
• Sword and Shield: You’ll find Relicanth in the first Expansion Pass by surfing on Ballimere Lake. 

Luvdisc

• National Dex Number: 370
• Category: Rendezvous Pokémon
• Type: Water-type.

Where to Find Luvdisc? 

You’ll find Luvdisc by fishing with a Good or a Super Rod in the following places: 

• Ruby, Sapphire, and Emerald: Route 128 and Ever Grande City. 
• Diamond, Pearl, Brilliant Diamond & Shining Pearl: Route 224 and Pokémon League. 
• HeartGold & SoulSilver:  Only by surfing on Route 27 during a swarm. 
• Black & White: Route 4 and 13, Driftveil City, Undella Town, and Undella Bay. 
• Black 2 & White 2: Routes 13 and 21, Seaside Cave, Undella Town, and Humilau City. 
• X & Y: Routes 8 and 12, Ambrette Town, Cyllage City, Shalour City, and Azure Bay. In this game, you’ll only need an Old Rod to find Luvdisc. 
• Omega Ruby & Alpha Sapphire: Route 128, Ever Grande City, and Victory Road.
• Sun, Moon, Ultra Sun & Ultra Moon: Route 9 and Melemele Sea. 

Finneon & Lumineon

Finneon 

• National Dex Number: 456
• Category: Wing Fish Pokémon. 
• Type: Water-type.

Where To Find Finneon? 

To get Finneon, you’ll have to fish with a Good Rod in the following places:  

• Diamond, Pearl, Brilliant Diamond & Shining Pearl: Routes 205, 218, 219, 220, and 221, Fuego Ironworks, Iron Island, Canalave City, and Valley Windworks.  
• Black & White: Routes 17 and 18, and P2 Laboratory. 
• Black 2 & White 2: Routes 17 and 18, P2 Laboratory, Virbank City, and Virbank Complex. 
• Omega Ruby & Alpha Sapphire: Routes from 122 to 134, but only as a hidden Pokémon. 
• Sun, Moon, Ultra Sun & Ultra Moon: Routes 1, 7, 8, 14, and 15, Hau’oli City, Melemele Sea, Kala’e Bay, Brooklet Hill, Hano Beach, and Secluded Shore. 

Lumineon 

• National Dex Number: 457
• Category: Neon Pokémon
• Type: Water-type.

When Finneon gets trained until Level 31, it’ll evolve into Lumineon. 

Battle Usage 

Sadly, Finneon and Lumineon didn’t make it to Sword and Shield, so there isn’t any updated strategy for them. As far as I remember, Lumineon was a decent Water-type to use in Gen 4’s adventure. Still, there are way better water-type Pokémon, like Floatzel.

Basculin & Basculegion

Unovian Basculin 

• National Dex Number: 550
• Category: Hostile Pokémon
• Type: Water-type.

Where to Find Basculin? 

Basculin can be found by fishing or surfing in the following places: 

• Black (Red-Striped) & White (Blue-Striped): Routes 1, 3, 6, 11, and 14, Striaton City, Wellspring Cave, Pinwheel Forest, Dragonspiral Tower, Challenger’s Cave, Victory Road, Village Bridge, Giant Chasm, Abundant Shrine, and Lostlorn Forest. 
• Black 2 (Red-Striped) & White 2 (Blue-Striped): Routes 1, 3, 6, 11, 13, 14, 19, 20, 22, and 23, Aspertia City, Floccesy Ranch, Relic Passage, Clay Tunnel, Dragonspiral Tower, Striaton City, Wellspring Cave, Pinwheel Forest, Undella Town, Humilau City, Victory Road, Village Bridge, Giant Chasm, Abundant Shrine, Nature Preserve, and Lostlorn Forest. 
• X & Y: Both Basculin can appear in the same places, but depending on the game, you’ll find them with a Good or a Super Rod. 

On X, if you fish with a Good Rod on Routes 15 and 16, Laverre City, Couriway Town, Frost Cavern, Pokémon Village, and Victory Road, you’ll get the Blue-Striped Basculin. While if you fish in the same places with a Super Rod, you can get the Red-Striped Basculin. 

The same happens on Y in the same places mentioned before, but Red-Striped Basculin will appear with a Good Rod, and Blue-Striped Basculin will get out of the water with a Super Rod. 

• Ultra Sun (Red-Striped) & Ultra Moon (Blue-Striped): Brooklet Hill, Malie Garden, and Vast Poni Canyon. 
• Sword (Red-Striped) & Shield (Blue-Striped): Hulbury, Motostoke Riverbank, North Lake Miloch, Snowslide Slope, Frigid Sea, Roaring-Sea Caves, Giant’s Bed, Giant’s Foot, and Ballimere Lake.  

Battle Usage 

If you are reviving your childhood days or want to try Black & White for the first time, I recommend using Basculin as your Water-type Pokémon. It isn’t the best on competitive terms. Still, it’s a great Pokémon for the adventure, with more than a decent Attack and a great Speed! 

Hisuian Basculin 

• National Dex Number: 550
• Category: Mellow Pokémon
• Type: Water-type.

Where to Find Hisuian Basculin? 

• Legends: Arceus: Tranquility Cove, Islespy Shore, Fabled Spring, Lake Acuity, and Heart’s Crag. 

Basculegion 

• National Dex Number: 902
• Category: Big Fish Pokémon
• Type: Water/Ghost-type.

When Hisuian Basculin uses a move with Recoil and loses at least 294 HP, it’ll evolve into Basculegion. 

What Happened to Basculegion? 

Basculegion’s story is a very sad one. Hisuian waters were dangerous, and such a passive and chill-out Pokémon as it was Hisuian Basculin, it didn’t have a chance on those territories. But when a fierce Basculin got severely injured by these rapids, the souls of the dead Basculins took on them, evolving into Basculegion. 

The Basculins decided to move to calmer waters, traveling to Unova. Unfortunately, as they adapted to the new waters, they lost their capability to evolve. 

Alomomola

• National Dex Number: 594
• Category: Caring Pokémon
• Type: Water-type. 

People used to think Alomomola was part of Luvdisc’s evolution line, but that’s not true. They don’t even have the same Category!

Where to Find Alomomola? 

You’ll find Alomomola by fishing with a Super Rod in the following places: 

• Black & White: Routes 4, 17, and 18, Driftveil City, and P2 Laboratory. 
• Black 2 & White 2: Routes 4, 17, 18, and 21, Virbank City, Virbank Complex, and P2 Laboratory. 
• X & Y: Shalour City and Azure Bay. 
• Omega Ruby & Alpha Sapphire: Routes from 122 to 134, but only as a hidden Pokémon. 
• Sun, Moon, Ultra Sun & Ultra Moon: Brooklet Hill. 

Tynamo, Eelektrik & Eelektross

Tynamo 

• National Dex Number: 602
• Category: EleFish Pokémon
• Type: Electric-type.

Where to Find Tynamo? 

You’ll find Tynamo in the following places: 

• Black & White: Chargestone Cave.
• Black 2 & White 2: Chargestone Cave and the Seaside Cave. 
• Omega Ruby & Alpha Sapphire: Tynamo only appears on Mirage Caves, exactly the ones near Fallarbor Town, Route 115, Fortree City, Route 129, Route 131, or Route 132. 
• Sun, Moon, Ultra Sun & Ultra Moon: Tynamo is only obtainable by breeding Eelektross, available at Poni Grove through the Island Scan, and only on Sundays. 

Eelektrik 

• National Dex Number: 603
• Category: EleFish Pokémon
• Type: Electric-type.

When Tynamo reached level 39, it’ll evolve into Eelektrik. 

Eelektross 

• National Dex Number: 604
• Category: EleFish Pokémon
• Type: Electric-type.

When Eelektrik gets exposed to a Thunder Stone, it’ll evolve into Eelektross. 

Battle Usage 

An Electric-type Pokémon with Levitate as its ability, making it immune to its only weakness? I want it on my team! Eelektross is a great Pokémon, and I’m sure it would appear on the highest tiers of the competitive system, but there’s a problem; it doesn’t appear in Sword and Shield. 

I remember using it on my Black & White team the last time I played the game, and I recommend using it with Crunch, Thunder, and Ice Fang! 

Stunfisk 

Unovian Stunfisk 

• National Dex Number: 618
• Category: Trap Pokémon
• Type: Electric/Ground-type. 

Where to Find Unovian Stunfisk

Unovian Stunfisk will appear by fishing or surfing in the following places: 

• Black, White, Black 2 & White 2: Route 8, Icirrus City, Moor of Icirrus. 
• X & Y: Routes 14 and 19, and on the Electric-type Friend Safari. 
• Ultra Sun & Ultra Moon: You’ll find it in the Ultra Space Wilds, in the Water World. 
• Sword and Shield: Regina, in the Isle of Armor, will give you an Unovian Stunfisk in exchange for a Galarian Stunfisk. 

Galarian Stunfisk 

• National Dex Number: 618
• Category: Trap Pokémon
• Type: Ground/Steel-type. 

Where to Find Galarian Stunfisk? 

• Sword and Shield: Slumbering Weald, Galar Mine No. 2, Dusty Bowl, and Lake of Outrage. 

Battle Usage 

Galarian Stunfisk isn’t a good Pokémon for competitive matches. It isn’t even the best Steel-type option, but it has something going for it, as it’s a Steel-type Pokémon that you can find early on the adventure. With its Steel-type and its great type combination, Stunfisk can do a lot for you when proving yourself in the Galarian Gym Challenge! 

Skrelp & Dragalge

Skrelp 

• National Dex Number: 690
• Category: Mock Kelp Pokémon
• Type: Poison/Water-type. 

Where to Find Skrelp? 

Skrelp can be found by fishing with a Good Rod in the following places: 

• Y: Route 8, Cyllage City, and Ambrette Town. 
• Omega Ruby: Skrelp appears as a hidden Pokémon in Routes 105 to 109. 
• Ultra Moon: The only way to get a Skrelp is by breeding Dragalge, which can be found on Poni Breaker Coast, but only on an ambush encounter.  
• Shield: Skrelp can only be found in the first expansion pass, on Workout Sea, Stepping-Stone Sea, Insular Sea, Honeycalm Sea, and Honeycalm Island. 

Dragalge 

• National Dex Number: 691
• Category: Mock Kelp Pokémon
• Type: Poison/Dragon-type. 

When Skrelp gets to Level 48, it’ll evolve into Dragalge. 

Battle Usage; Entry Hazard Setter Dragalge 

Dragalge is a powerful Pokémon in RU, the third-highest competitive tier. It’s a wonderful Entry Hazard Setter as it has access to Toxic Spikes, but that’s not all, as it’s very bulky, so it can act as your lead! 

Dragalge can do it perfectly with the following build: 

• Toxic Spikes
• Sludge Bomb
• Draco Meteor
• Flip Turn

With Black Sludge as its item, Adaptability as its Ability, and Modest as its Nature. 

• EVs: 252 HP / 252 SpA / 4 Spe

The first thing Dragalge will do as soon as it hits the battlefield is to set the Toxic Spikes. Then, you can use it as a pivot thanks to Flip Turn, which isn’t more than a Water-type U-turn. Sludge Bomb and Draco Meteor will be there if Dragalge is alone against the enemy! Not many people expect a Dragalge with Flip Turn, so it’s a great thing to use against Steel-types! 

Wishiwashi 

• National Dex Number: 746
• Category: Small Fry Pokémon.
• Type: Water-type. 

Where to Find Wishiwashi? 

Wishiwashi can be found by fishing in the following places: 

• Sun, Moon, Ultra Sun & Ultra Moon: Routes 7, 8, 9, 13, 14, and 15, Melemele Sea, Kala’e Bay, Brooklet Hill, Akala Outskirts, and Secluded Shore. 
• Sword & Shield: Route 9, Hulbury, West and East Lake Axewell, Axew’s Eye, Challenge Beach, Stepping-Stone Sea, Insular Sea, Honeycalm Island, Honeycalm Sea, Fields of Honor, Loop Lagoon. 

Battle Usage; Late Game Sweeper Wishiwashi 

School Wishiwashi is a fierce sweeper Pokémon in the lowest tiers of the competitive meta. It doesn’t get used in the highest tiers mostly because of its ability, Schooling, which makes School Wishiwashi separate when it gets to 25% of its HP. 

Other than that, Wishiwashi is a powerful Pokémon, and it can work with the following build: 

• Hydro Pump
• Flip Turn
• Ice Beam
• Earthquake

With Sitrus Berry as its item, Schooling as its ability, and Quiet as its Nature. 

• EVs: 252 HP / 128 Atk / 128 SpA

Wishiwashi can’t hit the battlefield until the opposite team’s Sweeper is down. Wishiwashi can withstand anything except for a strong hit of a Sweeper. 

Also, Wishiwashi will appreciate being protected by Light Screens and Reflects. If it has a Pokémon with Sleep Powder on its team, Wishiwashi can tear the opposite team apart. All its moves are entirely offensive, and it has Flip Turn as an escape rope in case it’s in a sketchy situation. 

Bruxish

• National Dex Number: 779
• Category: Gnash Teeth Pokémon.
• Type: Water/Psychic-type. 

Where to Find Bruxish? 

Bruxish only appears on Gen 7, in Sun, Moon, Ultra Sun & Ultra Moon, on Routes 13, 14, and 15, and Secluded Shore. 

Battle Usage 

Again, this is one of those Pokémon that got excluded from Sword and Shield without a good explanation. It’s annoying, as Bruxish is actually a great Pokémon, as it is a Physical Psychic-type Sweeper.

Arrokuda & Barraskewda 

Arrokuda

 

• National Dex Number: 846
• Category: Rush Pokémon.  
• Type: Water-type.

Where to Find Arrokuda? 

Arrokuda only appears on Sword & Shield, on Route 2, Hulbury, and Motostoke Riverbank. 

Barraskewda 

• National Dex Number: 847
• Category: Skewer Pokémon.  
• Type: Water-type.

When Arrokuda gets to level 26, it’ll evolve into Barraskewda. 

Battle Usage, Late Game Sweeper Barraskewda 

Barraskewda only stands out on its Attack and Speed, being able to destroy its enemies without having a chance to withstand an attack. 

With this setup, Barraskewda has been a constant presence in OU, the second-highest tier of the competitive meta, where it gets used as a Late Game Sweeper, mostly like Wishiwashi; it is the Pokémon you’ll use when you want to finish the match. 

Barraskewda can work with the following build: 

• Liquidation
• Brick Break
• Drill Run
• Ice Fang 

With Choice Band as its item, Swift Swim as its ability, and Adamant as its Nature. 

• EVs: 252 Atk / 252 Spe / 4 Def.

This build is entirely offensive, as the idea is to use Barraskewda to give the coup-de-grace to your opponent. Brick Break, aside from being a strong Fighting-type move, also works to break those annoying Light Screens and Reflects, which are very used on OU. 

If you have a Rain setter, Barraskewda can give some usage to its mostly useless (because it’s fast enough) Swift Swim ability. 

FAQs

Every Fish Pokemon: Conclusion

While most of these fish Pokémon are very interesting and have a constant presence in the Pokémon games, others, like Lumineon, Bruxish, or Eelektross, got discarded for unknown reasons.  I hope Game Freak adds all the Pokémon in their following games; I know they are a lot, but it’s because of these Pokémon that the Pokémon world feels real, and that’s the magic of these games. 

Thanks for exploring the PokéAquarium with me!
