LIMIT 4 PER ORDER. The one pictured is mature male with breeding coloration showing. Males are more colorful than females. You cannot request just males, but we can try to get you pair upon request, but we do not guarantee it. These are Central American Cichlids, which are often even more social than South American Cichlids. The amount of blue and red they develop when mature will vary. These are GREAT community fish, mostly non aggressive and do great in small communities of 3 to 7 fish. These are tank raised in our facility in Florida. These max out in size at around 3 inches.
