AquaSim

AquaSim is a cozy, living aquarium that stays with you while you use your computer.

No stress. No pressure. Just a peaceful world quietly evolving on your screen

Unlike traditional idle games, AquaSim is designed as a desktop companion, something you don’t “play” constantly, but something that lives alongside you.

Study, work, or relax while your fish grow, interact, and create a living ecosystem in real time.

What is AquaSim?

Take care of your aquarium at your own pace:

• Feed your fish and watch them grow
• Clean and maintain water quality
• Decorate your tank with meaningful items
• Discover new species and rare variations
• Observe natural behaviors, interactions, and breeding
