Sim Aquarium 3 [2025-2027]

opens for Patreon backers on April 10th.

Late Summer.

We heard you. Here is what we’ve been building. In SIM Aquarium 2 , fish reacted to the moment. In SIM Aquarium 3 , they react to history . We’ve implemented a lightweight "Genetic Memory" for each fish. If a neon tetra’s parent was born near the filter output, that offspring will instinctively seek out high-flow areas. If a cichlid lost a fight near the ceramic log, its descendants will avoid that zone entirely. sim aquarium 3
