+1 Drain Water Per Click Fish
Emptying a pool reveals fish at the bottom — the official description promises "rare and legendary Fish". More than 20 fish are now documented by name from gameplay footage, and in-game rarity labels run from Common up through Legendary, Mythic, Celestial and Secret. No public source publishes a complete roster or verified sell values — here's everything we could verify, honestly separated from what we couldn't.

Names and rarities above come from gameplay footage; the full roster, per-pool rarities, catch chances and verified sell values are not publicly documented yet. Any values mentioned are player-observed. No reliable public source documents this yet, so we show no number rather than a guess. Values will be added as soon as they can be verified.
How fish work, per sources
- Pools hide fish at the bottom — drain the pool to reach them.
- Sell fish for Cash (main currency) or display them in your aquarium for income every minute.
- Backpack space is limited; a full backpack sends you to the shop.
- Fish can spawn with a mutation (Gold ×2 up to Hole ×20) that multiplies value.
- World fish despawn on a timer — grab valuable spawns quickly.
- Fish have a weight in kg — the heaviest fish in your aquarium competes for "King" status (per gameplay footage).
- Each world has its own fish index; filling it (and collecting mutation variants) grants titles.
- Luck zones shown in footage run up to 1,000,000× luck and improve rare fish spawns.

Fish FAQ
How do you get fish in +1 Drain Water Per Click?
Drain a pool completely: fish sit at the bottom and can be picked up. From there you either sell them for Cash or display them in your aquarium, where they earn income every minute. Your backpack holds a limited number, so sell regularly.
Is there a full fish list with values?
Not a complete one. As of August 29, 2026 more than 20 fish names are documented from gameplay footage — Leviathan, The Bloop, Orca, Sunfish, Lion Fish, Sea Urchin, Julia and more — but no reliable source publishes the full roster, per-pool rarities, catch chances or verified sell values. We list every documented name, each labeled with its evidence level, instead of inventing a table.
What is the most valuable fish?
Unresolved. The largest sale values observed in footage are a Julia at roughly 88 million, an Orca at 12.3 million and a Bloop around 12 million — all player-observed, not verified stats. Secret-rarity fish exist in the deepest worlds and no values for them have been published. Mutated fish (e.g. Hole ×20) are worth far more than the same fish unmutated.
Should I sell fish or put them in the aquarium?
Selling gives Cash now; the aquarium pays that fish's value repeatedly over time (every minute per sources). Mutated fish earn the mutation multiplier in the aquarium too, which is why rare mutations are worth displaying.
