ARC Aquarium

Buy fish, raise them in real time, and sell them for profit. Breed your own,

decorate a tank that keeps earning, and collect every species at your own pace.

This is the FREE DEMO. The full game is on Steam.

🐠 RAISE AND SELL

- Every fish you buy arrives as an egg — hatch it and watch it grow in real time

- Feed your fish to speed up their growth

- A grown fish sells for far more than it cost

- Your collection permanently records every species you've raised

🥚 BREED YOUR OWN

- Pair two adult fish to produce eggs

- Raise a bloodline instead of buying every fish

🪸 BUILD THE TANK
