El Fish

El-Fish is a DOS title centered on aquarium simulation. Its core systems allow players to design a complete aquatic environment, from the substrate and background to the plants and the fish themselves.

Rather than using static assets, the game employs genetic algorithms to generate nearly all visual elements. This procedural approach governs the appearance and swimming animations of the fish, which users can catch, breed, and induce mutations in. The auditory atmosphere is also customizable, with software-generated music available in several styles.
