Blue-lipped Mouthbrooder Care Guide - Aquarium Tips, Diet & Breeding

The Blue-lipped Mouthbrooder is a small, robust African cichlid named for the blue or blue-grey colouring that can develop around the male’s lips. Males are generally more colourful, with warm yellow, orange or reddish tones in the fins and body, while females tend to be smaller and less vividly marked. Individual colour varies with mood, dominance and breeding condition.

This species has the compact, slightly deep-bodied shape typical of a dwarf mouthbrooder. It is active and observant, spending much of its time close to the bottom while inspecting the substrate, cover and other fish. Males can become territorial, particularly when displaying or guarding a spawning site, but the species is not usually as aggressive as many larger African cichlids.

In the wild, Blue-lipped Mouthbrooders are associated with shallow waters around the Lake Victoria region. Their habitat may include aquatic vegetation, leaf litter, sand, fine gravel and scattered rocks, giving them both feeding areas and places to retreat from danger.

Like other mouthbrooding cichlids, they show fascinating parental behaviour. The female carries the eggs and young in her mouth, making this species an appealing choice for aquarists interested in natural breeding strategies and the social behaviour of African cichlids.

The Blue-lipped Mouthbrooder is native to the Lake Victoria basin of East Africa, including parts of Uganda, Kenya and Tanzania. It inhabits shallow, warm freshwater environments with vegetation, marginal cover and areas of open substrate.

A minimum aquarium of around 60 litres is suitable for a small group, although a larger tank is preferable for multiple females or community housing. Aim for a footprint of at least 60 by 30 cm, with additional length and floor area especially useful for territorial males. Use sand or smooth fine gravel, arrange rocks and small caves to create separate territories, and add hardy plants or floating cover around the edges. Leave some open substrate for feeding and provide gentle filtration with well-oxygenated, stable water.

Males reach about 8 cm (3.1 inches), while females usually grow to around 6 cm (2.4 inches).

Blue-lipped Mouthbrooders are omnivorous and should receive a varied diet based on a quality small cichlid pellet or flake. Supplement this with frozen or live foods such as brine shrimp, daphnia, bloodworms and mosquito larvae, along with some spirulina-based food or finely chopped vegetable matter. Feed modest portions once or twice daily, removing uneaten food to protect water quality.

Blue-lipped Mouthbrooders can live with peaceful, similarly sized African fish such as robust livebearers, small rainbowfish and calm barbs, provided the aquarium is spacious and well structured. They may also work with other peaceful dwarf cichlids when territories are clearly separated. Avoid very timid fish, long-finned species, tiny slow-moving companions and aggressive or much larger cichlids. Keeping one male with two or more females helps spread territorial attention and reduces pressure on individual females.

Blue-lipped Mouthbrooders are maternal mouthbrooders that breed readily in suitable conditions. Keep one male with several females and provide caves, stones or dense cover around the breeding area. After spawning, the female collects the fertilised eggs in her mouth and incubates them for roughly 10 to 14 days, depending on temperature. She releases fully formed fry, which can be fed newly hatched brine shrimp, microworms and finely powdered fry food. The female may continue sheltering the young and allow them to return to her mouth when threatened.

Males are larger and more strongly coloured than females, often showing brighter blue around the lips and richer yellow, orange or red tones in the fins. Females are smaller, rounder when carrying eggs and generally more subdued in colour.
