Cozy Taskbar Aquarium
A tiny living aquarium for your taskbar. Hatch and breed fish that are painted live from their own genes, and let them keep you company while you work, study or play.
Coming to Steam in 2026. For Windows.
Alive at a glance.
Glance down and something lovely is happening: a puffer puffing, a curious fish following your cursor, a pearl bubble drifting up. Click the water and the fish race for the food.
The tank follows your real clock. When the lights go down, bioluminescent fish, lanterns and crystals start to glow.
No two fish alike.
There are no sprite sheets. Every fish is painted by code from its genes: 47 species, 36 patterns and 8 rare traits, with colors that blend from both parents.
Hunt for 37 hand-designed named layouts, and follow each fish’s parents, children and generation.
Every odd, shown first.
Eggs show their species and trait odds. Breeding pairs show every possible pattern, the trait chances and the rarity range, before you confirm.
Breeding never uses up the parents. They just rest for 10 minutes.

Quiet on your desktop.
Tankbar runs at 30 fps by default, and you can choose 15, 30 or 60. It pauses when it’s hidden, when your PC is locked and when it sleeps. Ghost mode lets every click pass straight through the tank.
It works fully offline, and saves on your PC with automatic backups.
