PC FISH: Taskbar Aquarium A Little Tank That Lives Beside Your Work

Write an email, browse, run a raid, and the tank keeps humming along in the corner: pixel fish drifting past plants and little ornaments, lo-fi music under it all. Hover over a fish and it pops up to meet your mouse. It is a desktop companion first, a game second, and it is happy being both.

You start with a few common fish and grow from there. Breed two fish and hope for something better; fuse ten into one for a shot at a higher rarity. Fish come in five rarity tiers, from common up to legendary and mythic, and every species has color variants, which is how the collection climbs past 450 fish and decorations. As your aquarium levels up it gets bigger, so you can display more fish and more decorations. Fair warning: the higher tiers come slowly, and the late rarities are a long grind. The early discovery pace is the fun part.

Every fish has value, and you can sell yours or buy someone else's on the Steam Community Market. Stuck on a species that refuses to hatch? Someone is probably selling it. Bred a high-grade variant nobody near you has? List it. Seasonal events add limited fish that can only be traded for once the season ends, which keeps the market lively and gives your breeding program a reason beyond the collection itself. If trading is not your thing, the tank works fine as a pure collect-and-watch idler.
