- Rift lake cichlids like greshake's zebra need hard, alkaline water and a busy, cichlid-only tank.
- Their pH needs don't quite meet (7.8–8.6 vs 5.5–7.5). Aim between the two and keep it steady.
- Rift lake cichlids like greshake's zebra need hard, alkaline water and a busy, cichlid-only tank.

Breeding
Maternal mouthbrooder (harem) · Moderate
A maternal mouthbrooder, spawned as a harem of one male and at least 3 females; the female carries the eggs for up to 3-4 weeks before releasing free-swimming fry.
Keep one male with 3-5 females; a lone female is harassed to exhaustion and two males will fight.
150-250 L rockwork tank with many caves, hard alkaline water (pH 7.8-8.6) and strong filtration. Keep a bare 60 L tank handy to move a holding female.
Stable warm water (26-28 C), regular water changes and a good male-to-female ratio; the male displays and leads a female to a flat rock or cave.
The female carries the eggs for up to 3-4 weeks. No sourced egg count found.
The female releases free-swimming fry after 3-4 weeks. Feed finely crushed flake, spirulina powder and newly hatched brine shrimp from day one; do small daily water changes. Remove the female after release so she can recover.
- Too few females so the male harasses them
- Mixing similar-looking mbuna that hybridise
- Soft or acidic water
Where it lives in the wild
The story of the greshake's zebra
A Lake Malawi mbuna known only from Makokola in the southeastern arm, where it lives on sediment-covered rocky reefs and feeds largely on plankton. Listed as Near Threatened because of its tiny range; an albino form exists in the hobby.
This zebra mbuna was described in 1984 by Meyer and Förster. Its ice-blue body and red-orange dorsal fin make it a showy fish. Like other Maylandia, it is a mouthbrooding algae grazer.
First described by Meyer & Förster in 1984.
- Males have a pale blue body with an orange-red top fin.
- Females are usually much plainer, often brownish.
- It belongs to the zebra mbuna group, which shows huge colour variation.
