Venustus Cichlid (Nimbochromis venustus) Breeding Guide
Overview
Nimbochromis venustus is a large, polygamous maternal mouthbrooder from Lake Malawi and an ambush predator that partially buries itself in the sand to lie motionless until prey approaches. Wild specimens reach up to about 25 cm, so breeding requires a spacious tank.
Sexing
Males grow larger and develop gaudier colouration than females, showing blue and yellow pigmentation across the body, while females remain plainer with the juvenile blotched pattern.
Conditioning
Keep the breeding group on its own and condition it on a high-quality, meat-based diet. Target conditions are around pH 8.0-8.5 and a temperature of about 25-27 °C (77-81 °F).
Breeding Setup
A breeding group of one male with three to six females is recommended. Use a tank of at least 48 inches in length, furnished with rocks to form caves and some large, flat rocks to act as spawning sites.
Spawning Behavior & Trigger
Spawning follows the familiar cichlid pattern: the female lays a line of eggs and moves away, allowing the male to take her place and fertilise them, after which she collects the eggs into her mouth.
Egg & Fry Care
The female carries a brood of up to about 120 eggs for around three weeks before releasing free-swimming fry. The fry are large enough to accept brine shrimp nauplii from release, and brood care by the female continues for roughly another ten days.
Common Challenges
Holding females are notorious for spitting out the brood early when stressed, so extreme care must be taken if the fish has to be moved. The species' size and predatory nature also demand a large, well-structured tank.
