How it feels

A gentle, low-effort aquarium simulator that sits quietly at the bottom of your screen, letting you build and maintain tanks while focusing on other tasks.

What players say

Players enjoy this as a low-attention idle game that runs on a second monitor, ideal for background play while working or watching videos. The fishing minigame to unlock new species is a highlight, though some want more fish and taller decorations for the endgame.
