Livingstoni
Nimbochromis livingstonii
Cichlidae
About
Livingstoni is a large predatory haplochromine cichlid endemic to Lake Malawi, where it hunts across the sandy margins and vegetated bays between rocky reefs. Its blotched cream-and-brown coat is not just camouflage but a lure: the fish will lie motionless on its side against the substrate, feigning death, until a small fish approaches to investigate the apparent corpse and is snapped up. The local name 'Kaligono', or sleeper, captures this unusual ambush strategy. Hardy and long-lived but boisterous and territorial, it needs a big, open aquarium with a sandy floor, 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. Feed carnivore or cichlid pellets plus frozen mysis, krill, prawn and lancefish; avoid fatty mammalian meats to limit the risk of Malawi bloat.

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.

Frequently asked questions
- What tank size does a Livingstoni need?
- A Livingstoni needs an aquarium of at least 350 litres (92.5 US gallons) with a footprint at least 150 cm (59.1 in) long — for this species, swimming length matters as much as raw volume.
- What water parameters does a Livingstoni need?
- Livingstoni does best at 24–28 °C (75.2–82.4 °F), pH 7.6–8.8 and a general hardness of 9–25 °dGH.
- What group size does a Livingstoni need?
- Livingstoni is a social species — keep a group of at least 4 so natural behaviour emerges and stress stays low.
- Is the Livingstoni suitable for beginners?
- Livingstoni sits in the middle of the difficulty scale — manageable for a careful beginner who has done the reading, but it has specific needs worth researching first.
