Tiny Aquarium: Idle Fish Tank

Tiny Aquarium is a cozy idle aquarium game. Raise fish, decorate your own fish tank and visit aquariums made by players around the world.

Start with a single egg in an empty tank. Hatch it, feed your fish and watch them grow in real time, even while the app is closed. A few relaxing minutes a day is enough, and your aquarium keeps growing while you're away.

Collect 120+ fish

Goldfish, koi, betta, axolotls, crabs, shrimp, sea turtles and many more: there's always a new species to find. Every fish in the FishDex comes with a fact about its real-life counterpart.

Breed rare fish

Pair your fish to hatch new ones. Every fish has its own genes, and rare traits like albino, glow or gigantism make some of them one of a kind.

Decorate your tank

Over 100 decorations: plants, corals, driftwood, a sunken ship and seasonal pieces. Pick the soil and background, and build the aquarium you actually want across several tanks.

Play together

Visit other players' aquariums and leave reactions, trade fish on the online market, and go fishing with friends in shared boat sessions.

Go fishing

Cast a line, reel in rare catches, upgrade your rod and boat, and bring your best fish home.

Relax at your own pace

No pressure and nothing to race. Daily quests and rewards give you something small to do each day, and seasonal events bring limited fish and decorations. Part aquarium simulator, part virtual pet, and your tank keeps running offline too.

One purchase. No ads and no in-app purchases. Cloud save keeps your aquarium safe across devices, and the game is available in 12 languages.
