AFK Aquarium: Idle Fish

Idle collection + defence

Build a tank. Defend the pearl.

Collect a ridiculous cast of pet fish, merge three matching friends into spectacular evolved forms, dress them in silly hats and send your strongest team into automatic battle.

12 fish species 100 waves Android

The loop

Calm at home. Chaos on defence.

01

Collect & merge

Open Mystery Fish Bags, discover distinct species and merge three matching fish into a stronger, more spectacular rank.

02

Build the Fin Guard

Choose a team with different attacks and elements, then watch them defend the Heart Pearl from waves of invading Gunk.

03

Make it yours

Feed and rename your fish, add decorations, collect thirty hats and build an aquarium full of visible progress.

One connected world

Every new fish helps the whole tank.

Your aquarium earns Shells while you are away. Bags add new characters, merges make them stronger and every improvement feeds a more capable defence team. Failed waves never destroy fish or erase progress.

“A cosy aquarium with a very silly security team.”
