Tiny Aquarium: Idle Fish Tank

Your fish keep growing even while you're away. Collect 120+ fish, decorate your tank, and unwind a few minutes at a time.

Tiny Aquarium is a relaxing fishkeeping game you can play at your own pace. Start with a single egg in an empty tank and slowly build it into something that's all yours. Hatch, breed, and catch fish, then decorate the tank however you like.

Collecting is the heart of it. There are 120+ fish to find, from real-world species to ones that only exist here, and new fish get added regularly. Some you'll get right away. Others you'll be chasing for a long time. Each one comes with a fact about its real-life counterpart, so you pick up a little as you go.

When you want company, visit other players' tanks, trade fish, and join live events. Or keep it to yourself. The game works either way.

Cast a line in the fishing minigame, upgrade your rod and boat, and go after the rarest catches. Build the aquarium you actually want.
