About This 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.
