Tiny Aquarium: Idle Fish Tank

Your fish keep growing while you're away. Hatch eggs, breed rare fish and make the tank your own.

Tiny Aquarium is a calm fish tank game you can play a few minutes at a time. You start with one egg in an empty tank. Feed your fish, collect the coins they make and spend them on new fish and decorations.

COLLECT 120+ FISH

Goldfish, koi, bettas, axolotls, clownfish, sea turtles, sharks, dolphins and plenty of fish you won't find anywhere else. Every fish comes with a short fact about the real animal.

BREED FOR RARE TRAITS

Fish pass their genes on to their young. With a little patience you can breed fish with rare traits, like albino or giant fish, then sell your best ones to other players on the market.

DECORATE YOUR WAY

Over 100 decorations, plus backgrounds and soils, so no two tanks look the same.

GO FISHING

Cast a line in the fishing minigame, upgrade your rod and boat, and head out with other players.
