About PC FISH
Everything you need to know about the game, its developer, platforms and requirements.
The Game
PC FISH: Taskbar Aquarium is a cozy pixel-art idle game that transforms your desktop into a living, interactive aquarium. Developed by Korean indie studio NANOO (나누컴퍼니) and released on Steam on August 14, 2026, the game quickly gained a dedicated following — particularly in Japan, where it went viral in late August 2026 with concurrent player counts surging roughly 50-fold from launch.
At its core, PC FISH revolves around three interconnected gameplay loops: Raise, Collect, and Trade. Players raise over 450 species of fish across five rarity tiers (Common, Uncommon, Rare, Legendary, Mythic), breed them to discover new variants and higher-rarity offspring, and export their fish to the Steam Community Market for real wallet funds.
The game's signature feature is its desktop companion mode, which shrinks the aquarium into a compact window that lives on your taskbar or screen corner. Fish continue to swim, earn currency, and progress even while you work, browse, or play other games — accompanied by a relaxing lo-fi soundtrack.
