Breeding Paracyprichromis brieni
Breeding guide for Paracyprichromis brieni, a peaceful Tanganyikan maternal mouthbrooder that spawns against rocky walls in 5-25 egg broods.
Overview
Paracyprichromis brieni is a slender, peaceful cichlid endemic to Lake Tanganyika and quite widespread in the lake, reaching a standard length of around 11 cm. It is a polygamous maternal mouthbrooder. Unlike open-water Cyprichromis, males form cave territories and the species spawns against rocky walls, often hanging upside down beneath ledges.
Sexing
Males are more colourful than females and develop longer extensions to the caudal fin, making mature males relatively easy to distinguish within a settled group.
Conditioning
The species is a small-mouthed zooplankton feeder, so live and frozen foods should form the bulk of the diet. Maintain a group in hard, alkaline water; Seriously Fish notes a breeding range of pH 8.0-9.0 at slightly cooler temperatures suits spawning, within the general 24-27 °C range.
Breeding Setup
Keep a shoal of at least eight fish with several females per male. Provide rocky structure with caves and vertical walls, as males establish territories there and can be seen hanging vertically against the rock or upside down beneath overhangs.
Spawning Behavior & Trigger
The female positions head-down against a rock wall while the male sits just above her, and the pair release eggs and sperm together. They continue until the female holds the clutch in her buccal cavity. Stable hard, alkaline water in the recommended breeding range triggers spawning.
Egg & Fry Care
The female accumulates 5-25 eggs in the mouth and carries the brood for around three to four weeks before releasing free-swimming fry. The fry can be reared on small live and frozen foods after release.
Common Challenges
The species is peaceful and retiring, so it can be intimidated by boisterous tankmates and may withhold spawning under stress. Providing a calm setting, a large enough group and the correct rocky territory layout are the keys to success.
