About Idlequarium
Idlequarium is a desktop aquarium game where you build and manage a tank of fish. You can place the aquarium anywhere on your screen, zoom in to view your fish or out to focus on other work, and leave it running while you are away as your fish grow.
Fish and tasks
Draw Fish Packs to unlock over a hundred freshwater and saltwater species, from Clown Knifefish to Discus. You may also hatch a mythical, ultra-rare fish. Complete management tasks to earn coins, decorations and resources, and use an Auto-Feeder Ticket to automate feeding.
Tanks and decorations
Choose from six tank styles and nearly a hundred decorations. Decoration Packs unlock rare items, and decorations can increase feeding XP and fish growth rates. You can shape the aquarium around your own preferences, from blooming cherry blossoms to a black dragon.
Manage your aquarium
Sell mature fish to fund upgrades for your tank and decorations. You can decide whether to fill the tank with fish first or focus on its appearance.
