Developer description

Quoted from the Steam store page. Read the full description

These are not pets. They are specimens. In Tank of the Fittest, you take control of an industrial aquarium on the edge of collapse. Twist heat, pH, oxygen, and pollution to create deliberate survival pressure, then watch ordinary fish become casualties, predators, or evolving anomalies.Turn the tank into a selection engine The environment is not a comfort checklist. It is your primary tool. Raise the heat, shift the pH, starve the water of oxygen, or let pollution spread to drive different specimens toward different outcomes.Make death part of the experiment The weak leave behind food and biological material. Their remains attract scavengers, feed predators, alter pollution, and keep the ecosystem moving. One death can strengthen a hunter or tip the entire tank into a new collapse.Build around the survivors Specimens gain traits, form synergies, and follow distinct evolution paths in response to clear, predictable pressures. Commit to a few focused build paths and turn one survivor into an apex specimen dangerous enough to dominate the entire tank.Archive what the tank creates…
