Cichlasoma Tetracanthus Cuban Cichlid 5cm

Overview

The Cuban Cichlid, now placed in the genus Nandopsis, is a stocky Caribbean cichlid with a pearly cream to grey body peppered with dark speckles and bold blotches. Wild fish come from Cuban rivers, lakes and brackish coastal waters. It suits keepers who want a characterful, moderately aggressive Central American style cichlid for a species or robust cichlid tank.

Final Notes

These fish grow quickly from juveniles and pairs need a tank at least 120 cm long with rockwork, caves and open sand for digging. Sexing is difficult until adult, when males are larger with longer fin tips. Aquarium spawning is uncommon but pairs become fiercely protective when it happens. Hard, alkaline water and strong filtration keep them in peak colour, and they reward patient keepers with plenty of personality.
