About the Game

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

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.

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 

Key Features:

  • Real-Time Simulation

    Your aquarium continues evolving even when you're not actively playing.

  • Breeding
    Fish reproduce with variation, creating unique and rare outcomes

  • 140+ Decorations
    Some objects aren't just visual,  they affect oxygen, happiness, and ecosystem balance

  • Bestiary Collection
    Track species, discover variants, and complete your aquatic collection

  • Organic Progression
    No forced missions, it gently rewards curiosity and care.

Perfect for students, developers, designers, streamers, or anyone who wants a living piece of calm on their desktop.
Thank you for checking out AquaSim!
