What is Lofi aquarium?

In this idle aquarium sim, fish grow while you study or work, and completed Pomodoro timers earn tomatoes that speed their growth. You can keep and name mature fish or sell them for coins to draw new fish at random and decorate your tanks. Lo-fi music, white noise, and task lists accompany the timer.

For you if...

+you want a focus timer alongside idle gameplay
+you like collecting fish and decorating aquarium tanks

Not for you if...

−you want hands-on play instead of an idle routine
−you prefer choosing fish over drawing random species
