You manage an aquarium, buying fish packs with in-game money and hatching the fish inside. Fish grow in real time, and you can sell them for profit or keep adult fish to generate income.
Feeding fish speeds up their growth. You can also upgrade tanks and fish food as you earn money, then use your profits to unlock additional fish packs and aquarium space.
Collect fish across freshwater and saltwater tanks, including rare and alternate-color variants. Customize your aquariums with options such as lighting, pebbles, decorations, and tank names.
Players who enjoy Chillquarium often praise its cute fish, varied designs, calming presentation, and suitability as a background game to check on occasionally. Collecting new species and variants is a draw for some, though others find the core loop repetitive and the pursuit of rare fish slow and grind-heavy.
Chillquarium is a relaxing idle game, where you buy fish and raise them in real time, then sell them to turn a profit or keep them around to earn money through ticket sales!
