AquaSim

WISHLIST on >>AquaSim Steampage<<

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 

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

  • 135+ Decorations
    Some objects aren't just visual,  they affect oxygen, temperature, 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.

That is beautiful! A lot of work in there definitely 

I wonder, is it accurate in terms of food to fish relation? I have no idea about the fish but if it is not random it is twice as cool :D

Thank you!!

Yeah, it’s actually not random at all 😄

I tried to make the food system loosely reflect real-life feeding behaviors, so different species have preferred food types depending on how they behave in nature.

For example:

  • Smaller or common fish like Goldfish, Tetras, and Angelfish eat flakes
  • Bottom feeders and heavier fish prefer sinking pellets
  • Some species (like Otos or Surgeonfish) eat algae
  • Predators like sharks or piranhas eat meat
  • Jellyfish and some exotic species feed on plankton-like food

So while it’s simplified for gameplay, there is logic behind it. ❤️

I wanted it to feel cozy and accessible, but still have that “oh, this actually makes sense” moment 🙂
