FISHPOND

FishPond is a pond-building sim where biology actually compounds. Stock species into a living food web. Manage oxygen, predation, and diversity to keep things alive—then start pushing the system. Breed lineages across 12 inheritable traits. Unlock genetic tools. Automate harvesting. Expand your world. Every fish has AI-driven behavior, a real genome, and a place in the food chain. Every population shift changes the music in real time. Every upgrade makes the whole thing run a little more like a machine—until you realize the machine is alive.
