The Dark Electric Ram resembles the Moon Dragon Ram, but instead of a gold face/head, it has a dark gray one with an electric blue body. This gray color may darken as the fish matures. There is a chance that they will be long fin or have the long fin gene. M. Ramirezi is a species of tropical fish that like it extra warm, with an ideal temperature of at least 82F. They can get quite territorial with other fish, especially their own kind. It’s best to have a lot of plants or other decorations to act as visual barriers in order to reduce aggression.
