Buffalohead Cichlid
Steatocranus casuarius
Cichlidae

About
The buffalohead, or lionhead, cichlid is an unusual bottom-dwelling species from the fast-flowing rapids of the lower Congo River and Pool Malebo. Adapted to turbulent, highly oxygenated water, it has a reduced swim bladder and hops along the substrate in short, comical bursts rather than swimming freely. Mature males develop a pronounced fatty nuchal hump that gives the fish its name. Territorial but not overtly aggressive, it forms strong monogamous pairs and spawns in caves.
Care
Keep a bonded pair in a tank of 110 L or more with strong flow, powerful oxygenation, a sand base and plenty of rock caves. Digs actively, so anchor hardscape and use tough plants like Anubias tied to wood or stone. Fit a secure lid.
Diet
Omnivore that grazes algae and aufwuchs in nature; in the aquarium feed sinking pellets and flakes plus frozen bloodworm, brine shrimp and daphnia, with some vegetable matter.

Telling males from females
What works for this species, most reliable first.
- Extended finsStrong · from about 8 months, and later in a suppressed male
On many cichlids and killifish the male's dorsal and anal fins draw out into trailing points as he matures, while the female's stay rounded.
- VentingA hint only · only on a mature fish, easiest when she is in breeding condition
The method breeders use when the answer has to be right. Hold the fish upside down in a wet hand or soft net and look at the two openings ahead of the anal fin. The forward one is the anus; the one behind it is what you are reading.
- Adult sizeA hint only · only across animals of the same age
In many cichlids, catfish and loaches one sex simply grows larger — usually the male, though there are well-known reversals.
