Breeding Melanochromis parallelus (Parallel Stripe Mbuna)

Melanochromis parallelus is a maternal mouthbrooding mbuna from Lake Malawi with strong sexual dichromatism. The female incubates eggs and fry in her mouth.

Overview

Melanochromis parallelus is a rock-dwelling mbuna cichlid of Lake Malawi (Wikipedia). The genus Melanochromis usually displays strong sexual dichromatism, and its females are mouthbrooders (Wikipedia, FishBase). As with other Lake Malawi mbuna, reproduction follows maternal mouthbrooding in hard, alkaline water.

Sexing

The genus shows strong sexual dichromatism (Wikipedia). In this species the colour pattern of the two parallel stripes differs between sexes, which aids identification of males and females once mature; mature, dominant males are the most strongly coloured.

Conditioning

As a Lake Malawi mbuna the species requires hard, alkaline water consistent with the lake (Wikipedia). Condition adults on an omnivorous diet that includes vegetable matter, in line with the aufwuchs-based feeding typical of rock-dwelling mbuna. Stable warm temperatures support breeding.

Breeding Setup

Provide abundant rockwork to create territories and line-of-sight breaks, as is standard for mbuna. Because the species is aggressive and territorial, stocking a dominant male with several females (harem) helps spread aggression. Sand substrate suits its rock-and-sand habitat.

Spawning Behavior & Trigger

Reproduction follows the mbuna maternal mouthbrooding pattern: the female takes the eggs into her mouth, where they are fertilised and incubated (FishBase; Wikipedia for the genus). Warm, stable, hard alkaline water and an established territory trigger spawning.

Egg & Fry Care

The female incubates the eggs and developing fry in her mouth and releases free-swimming young that quickly seek shelter among rocks, as documented for Lake Malawi mbuna. Released fry accept fine first foods. Brooding females may be isolated to protect the brood.

Common Challenges

Aggression is the main difficulty: this is an aggressive, territorial mbuna best kept with robust, similarly assertive tankmates and not with delicate community fish. Hybridisation risk also means keeping it apart from closely related Melanochromis is advisable.
