Little Aquarium

Little Aquarium is an idle game where you build and care for an underwater world. Buy and feed fish in real time, then sell them to earn money and grow your aquarium. You can collect rare species and color variants, and decorate your tank.

Collect and raise fish

Collect a variety of fish through a gacha system, including super-rare fish with special effects. Feed and raise them to grow them, then sell them for money. A feeding frenzy can make your fish grow massively.

Customize your tank

Personalize your tank with decorations and special environmental effects. The game also displays a fish tank on your desktop while you work without disrupting your workflow, and your progress in the game follows your progress through the day.
