Species Profiles
Convict Cichlid
Amatitlania nigrofasciata
Convict cichlids are tough, prolific Central American cichlids with distinctive black and white vertical stripes — earning them the 'convict' name. They are extremely hardy, breed readily (almost uncontrollably), and are highly aggressive for their size, especially when protecting fry. They are excellent for beginners who want to keep cichlids but should not be mixed with peaceful community fish.
