Red Terror Cichlids are quite popular and desirable in the aquarium keeping hobby. They are also called Festae Cichlids and come from South America. These fish get quite large and a 125 gallon or 6 foot tank would be the recommended minimum.
Red Terrors live up to their names and despite being beautiful they are horribly aggressive with each other and other fish. This is not an aquarium fish for the inexperienced. Males can also be terrible towards females.
