Black Nasty Cichlid

The Black Nasty Cichlid, Nandopsis haitiensis, is a powerful island cichlid from Hispaniola with bold markings and a commanding presence. Its pale, patterned appearance can change dramatically with mood and maturity; breeding females may become almost entirely black. This is a rewarding display fish for an experienced keeper prepared for a large, highly territorial adult.

Aquarium & care

Plan for an adult around 35–40 cm (14–16 in), with females generally smaller. We recommend at least 125 US gallons (475 L) for one adult, with a broad footprint around 180 × 60 cm (6 × 2 ft); a pair requires substantially more room. Maintain stable water around 27–28°C (81–82°F), pH 7.0–8.0, and moderate to hard mineral content. Use strong biological filtration, good aeration, and regular water changes matched carefully to the aquarium. Secure large shelters and rocks against digging, and leave clear swimming space.

Feeding

Feed a varied omnivore diet built around quality cichlid pellets with plant ingredients. Include spirulina foods and suitable vegetables, with modest portions of frozen invertebrates for variety. Avoid making rich meaty foods the entire diet, and remove leftovers promptly.

Temperament & tankmates

A dedicated aquarium is the safest choice. Small fish are unsuitable, and even robust cichlids may be attacked. Pairing requires close observation, separate retreats, and a ready means of separating the fish; breeding aggression can extend to the partner.
