About this game
The developer's description, from the game's Steam store page.
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!
