Anime Expeditions has a fishing mechanic with real rewards attached to it. The Anime Expeditions fish index covers 18 fish across five maps, each with its own rarity tier. Higher rarity fish give more EXP. Catching them all ties directly into the Tidal Siege event. Here is every fish, where to find it, and how rare it is.

What Is the Rarest Fish in the Anime Expeditions Fish Index
Coopfin is the only Legendary fish in the entire index. It spawns in both the Lobby and Tidal Siege maps. The Legendary rarity makes it the hardest to catch but also the highest EXP reward per catch in the current fish index.
Shellphone Snail, Rainbow Fish, and Sword Fish sit at Epic rarity — the next tier down. These are worth prioritizing alongside Coopfin for players trying to level Fishing EXP as fast as possible.
Higher rarity equals more EXP per catch. A Common Blue Tang gives the least. A Legendary Coopfin gives the most. The gap between rarity tiers is meaningful enough that chasing higher-rarity fish is always the faster path to leveling up Fishing compared to grinding Common ones.
The EXP from fishing counts toward the Fishing level — a separate progression system from the main account level. Leveling it up unlocks additional fishing-related rewards and contributes to completing the Tidal Siege event objectives.

Where to Fish for the Best Results
The Lobby and Tidal Siege maps have the most high-rarity options. Coopfin, Shellphone Snail, Fusion Fish, Prize Fish, Mirror Fish, and Booster Fish all appear in those two maps. Staying in the Lobby or Tidal Siege zone gives access to both the rarest fish and a solid mix of mid-rarity catches.
Flower Forest and East Town each have one Epic fish — Rainbow Fish and Sword Fish respectively. These are worth visiting for variety but do not match the overall rarity density of the Lobby and Tidal Siege maps.
Fishing is not just a side mechanic — it ties directly into the Tidal Siege event. Completing the event requires catching fish as part of the objectives. Players who skip fishing entirely will find the Tidal Siege event harder to complete without the Fishing EXP and catches needed to progress through it.
The mechanic also rewards patience. Higher rarity fish are less common per cast. Staying in one spot and fishing consistently in the right map builds EXP faster than hopping between locations looking for specific fish.
Final Thoughts
The Anime Expeditions fish index has 18 fish across five maps. Coopfin is the only Legendary. Stay in the Lobby or Tidal Siege zone for the best mix of high-rarity options. Focus catches on Epic and Legendary fish for the fastest Fishing EXP gains and the smoothest path through the Tidal Siege event.
