Tiny Aquarium: Social Fishkeeping is now available for Windows, macOS, and Linux on Steam, offering the chance to raise some virtual fish to live among the icons on your Windows desktop. Give someone an aquarium and they can eat for life, or something like that. The Release Trailer introduces the voxel-powered proceedings, and the game is 10% off for the next week. There's a playable demo to try and get you hooked, and this only lists Windows support. Here's word:
A happy aquarium that lives at the bottom of your screen! Tiny Aquarium is a social idle simulator that keeps growing, even when offline. Hatch, sell fish, decorate, go fishin’, and visit your friends’ aquariums with bite-sized daily sessions.
