Cichlasoma nigrofasciatum

The convict cichlid is a territorial fish which you will often find playing bulldozers in your aquarium! It is best therefore to avoid plants or delicately positioned rockwork. Selective breeding has gradually evolved a xanthochromic (golden) variety, which is just as belligerent. Both strains can interbreed with the redheaded cichlid, but the hybrids inherit the convict's behavior patterns. Size: 15-20 cm.
