About the game
Idlequarium is a casual simulation in which players breed small fish to collect coins, buy decorations, and put together a personalized aquarium. The tank can be placed anywhere on the desktop, so players can check in on it during short breaks from work or study. NutsX developed the game, which Gamersky Games released in 2025.
