Fishsie: Cozy Aquarium

Feed them, breed them, name them, and decorate a tank that's yours. 37 species, 65 decorations, no account and no ads — and it plays offline.

Fishsie is a cozy pocket aquarium. Raise happy fish, breed brand-new ones, and decorate a tank that is entirely yours — with no account and no ads.

Open it for ten seconds while the kettle boils, or sit and watch the light move through the water. Nothing here is in a hurry.

WHAT YOU DO • Feed your fish, and drag a finger so they follow you — happy fish leave coins behind • Collect 37 species, from a clownfish to a leafy sea dragon, an octopus and a whale • Breed pairs and hatch eggs: babies inherit both parents' colours and abilities, so a new fish is genuinely new • Decorate with 65 corals, plants, rocks, shells and shipwrecks — drag anything exactly where you want it • Recolour and rename every fish, and paint the water and the sand to match • Expand the tank up to five times its size, for a shoal of up to 80 • Fill the Fishdex, unlock nine achievements, and keep a daily streak going • Take a cinematic underwater tour, record a GIF of it, and share a picture of your tank

IT PLAYS OFFLINE Your aquarium lives on this device. On a plane, underground, with no signal at all — it opens, your fish are there, and they have been getting on without you.

PRIVATE BY DESIGN No account. No sign-up. No profile. No ads. No trackers. We collect no personal data, because there is no server for it to go to: your tank is stored in your own device's storage, and we could not read it if we wanted to. That makes this a safe game to hand to a child.

ONE PURCHASE, AND THAT IS ALL No ads, no in-app purchases, no subscription, nothing locked behind a second payment. Every fish, every decoration and every tank upgrade is earned by playing.

IN YOUR LANGUAGE English, Spanish, French, German, Portuguese, Chinese, Japanese, Arabic and Hindi.

And once you have unlocked every achievement, the shop will offer you something else entirely.

ALSO FREE IN YOUR BROWSER Fishsie began as a browser game and still is one. Play it free at www.fishsie.com, on any device, with nothing to install — try the whole thing before you buy. Buying the app puts the same tank on your home screen and supports a solo developer in Seattle.
