Convict cichlids are easily maintained and bred in aquariums. The aquarium should be decorated to mimic the natural environment and should include rocks and artificial caves for breeding. The species is an unfussy omnivore and most types of prepared fish foods are readily accepted. The species will also consume aquarium plants. Convict cichlids are aggressively territorial during breeding and pairs are best kept alone in suitably sized aquariums. It has been suggested that brood care is reduced in aquarium strains. Due to the tendency of the species to dig, external filtration is recommended over undergravel filter systems. The relatively small size of this species, along with ease of keeping and breeding, make the convict an ideal cichlid for beginners and advanced aquarists alike interested in observing pair bonds and brood care in the aquarium.
