Play El Fish Online
You breed mutant fish with bizarre traits, watching their genetics play out in real time—some swim gracefully, others flail like they forgot how to be fish.

El Fish came out in 1993 as part of the MS-DOS Classic Games series, developed by Maxis Software. It was one of those oddball titles from the early PC gaming days, a time when developers experimented with simulation in ways that didn't always involve cities or theme parks.
You play as a kind of aquatic geneticist, designing fish by mixing and matching body parts, colors, and behaviors. The main goal is to create interesting or viable creatures and release them into a small tank ecosystem to see how they interact. Signature mechanics include splicing traits from a library of options and observing how your creations swim, eat, or sometimes just bump into the glass. The pacing is slow and observational; there's no pressure beyond your own curiosity. It feels like tinkering with a digital aquarium where you never quite know what you'll end up with.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
