Breeding Maylandia zebra (Malawi Zebra)

Maylandia zebra is a maternal mouthbrooding mbuna. The female holds up to ~60 eggs and fry for 18-24 days, fasting while she broods, then releases free-swimming young.

Overview

Maylandia zebra (also written Metriaclima zebra) is the wild-type 'zebra' mbuna endemic to Lake Malawi, occurring in rocky areas at depths of about 6-28 m (Wikipedia). It is a maternal mouthbrooding cichlid that largely feeds on aufwuchs, the algae-based community on rock surfaces (Wikipedia). Many local colour morphs exist.

Sexing

Males have bright blue bodies with up to eight grey/black bars and either a dark or a blue head depending on form, while females occur in two morphs: a pale brownish-grey type and a dark brown to black type with blue highlights (Wikipedia). Mature dominant males show the strongest blue colour.

Conditioning

FishBase records 22-28 °C and a high pH around 8.0 for the species, reflecting Lake Malawi's hard, alkaline water. Feed an aufwuchs-style, vegetable-rich omnivorous diet plus zooplankton and small invertebrates, as taken in the wild (Wikipedia).

Breeding Setup

Provide rockwork for territories and a sand substrate. As a territorial mbuna, stocking a dominant male with several females (harem) spreads aggression. Hard, alkaline, warm water within the documented range supports spawning.

Spawning Behavior & Trigger

Spawning follows the maternal mouthbrooding pattern; the female produces up to about 60 eggs (FishBase). Research notes that a male's preference in mate colour is best predicted by the colour morph of his mother (Wikipedia), highlighting the role of female colour morphs in mate choice.

Egg & Fry Care

The female incubates the eggs and young in her mouth for 18 to 24 days, during which she does not feed and loses weight; once sufficiently developed, the fry are expelled into open water and quickly find shelter (Wikipedia). Released fry accept fine first foods.

Common Challenges

Aggression and the need for hard alkaline water are the main considerations; brooding females may be moved to a separate space so they are not harassed while fasting. Avoid mixing with delicate community fish.
