Venustus (Giraffe Cichlid)
Nimbochromis venustus
Cichlidae
About
The venustus, or giraffe cichlid, is a large predatory haplochromine endemic to Lake Malawi, where it patrols the sandy zones between rocky reefs in search of prey. It takes its common name from the bold chestnut blotches scattered over a pale body, while dominant males flush with an electric blue face and yellow forehead stripe. A patient ambush hunter, it will lie partly buried in the sand and even feign death to draw small fish within striking range. Hardy and long-lived but boisterous and territorial, it needs a big, open aquarium with sand, sturdy rockwork and hard, alkaline water.
Care
Keep in a large, open tank of 350 L or more (150 cm length ideal) with a sandy bottom, robust rockwork and hard, alkaline water at pH 7.8-8.5. Best as one male with several females alongside similarly sized, robust Malawi haps. A predator: never mix with fish small enough to be eaten.
Diet
Carnivorous ambush hunter of small fish and invertebrates. Feed carnivore or cichlid pellets plus frozen mysis, krill, prawn and lancefish; avoid fatty mammalian meats to limit bloat risk.

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.
