ChillTank

Your own little world. One fish at a time.
Build your own little underwater escape. Collect colorful fish, raise new generations, and decorate three cozy 3D habitats. Feed, grow, breed, or simply enjoy the view — a relaxing singleplayer aquarium, playable offline.

Find your favorite kind of quiet. Explore the sunlit waters of the Great Barrier Reef, the lush lagoon of Bora Bora, and the woodland calm of Redwood Forest. Each habitat is a new home for your growing collection. Much more habitats to come!

Start with an empty habitat and find your first fish in the FishShop. Feed them, watch them grow, and discover different colors, skins and traits. Keep an eye out for rarer shop arrivals — your next favorite might be waiting.

Unlock your breeder license, choose your pair, and give a new generation a home. Follow your breeding history and enjoy the reveal: a fresh fish, a new combination, and another reason to look a little closer.

Turn a habitat into your habitat. Shop for plants, rocks and decorations, unpack your deliveries, then place and rearrange your finds in Build Mode. Create a little hiding spot, a leafy corner, or a whole underwater garden.

In the FishShop you can buy more fish, food, decor and muuuch more!! Do note prices and fees are sometimes outrageous!

Stay for another feeding, make one last adjustment, or simply watch your fish drift by. Shifting light, weather and rippling water bring your little world to life. A cozy singleplayer aquarium to settle into at your own pace.
