Recommended Jun 19, 2026

If you're into games like Chillquarium, you'll definitely like this one. Still early access and room to grow, and hoping to see more species and tanks added in the future. Lots of potential here.

Recommended Jun 6, 2026

Omniquarium is a very laid back game that you do not have to do much but click the mouse a few times a few minutes. You can get a huge population of fish in no time, upgrades are easy to obtain and I am excited to see what updates bring to the game's atmosphere!
