PITCH
A cozy fishkeeping game on Steam: collect, grow and breed colourful fish, build a habitat that feels like home, and find your own kind of calm.

SHORT
ChillTank is a cozy fishkeeping game about collecting colourful fish and creating a little underwater world of your own. Feed your favourites, watch them grow, discover skins and traits, and welcome a new generation through breeding. Shape and decorate habitats, cast a line, run your fish shop and visit the Sharkabees auction room. The full game is in development for Steam on Windows, macOS and Linux / SteamOS, with offline singleplayer play and local saves. A free Steam demo offers selected content.

MEDIUM
Make a little room for wonder. ChillTank brings fish collecting, care and breeding together in a relaxing low-poly world. Find fish with their own skins and traits, feed your favourites, watch them grow and choose a pair to raise the next generation.

Create a home for your collection with habitat tools, plants, rocks and decorations. Explore forest hideaways, tropical shores, Japanese gardens and life beneath the reef as light and weather change around you. Follow your curiosity into fishing, meet visiting collectors in your own fish shop, or watch the bids in the Sharkabees auction room.

ChillTank is developed and published by Chillwatch, the independent project of Ramón de Smit in Germany. The full game is in development for Steam on Windows, macOS and Linux / SteamOS. It is designed for offline singleplayer play with local progress and multiple saves. A free Steam demo provides a smaller selection of fish and content; see Steam for current availability and demo details.

LONG
Your aquarium. Your pace. ChillTank invites you to build a little underwater retreat, one fish and one decoration at a time. It combines fish collecting, care and breeding with creative habitat building in a colourful low-poly world.

Discover fish with individual skins and traits. Feed your favourites, follow their growth and progression, and make room for one more arrival. Unlock breeding, choose a pair and welcome the next generation. Each fish family brings another combination to discover and another favourite to raise.

Make a habitat feel like home. Shape the shoreline, place plants and rocks, add decorations and find a view you want to return to. Forest hideaways, tropical shores, Japanese gardens and colourful reefs offer different kinds of quiet. Changing light, weather and a day-night cycle bring the little worlds to life.

There is more to follow beneath the surface. Cast a line, welcome visiting collectors to your own fish shop, or join the Sharkabees auction room and see which fish catches your eye. Collect, create and explore at your own pace.
