Maylandia estherae OB

Maylandia estherae OB is the orange-blotched colour morph of the Red Zebra cichlid, one of the most instantly recognisable and beloved mbuna in the aquarium trade. The OB gene produces irregular dark blotches over a vivid orange-red base colouration — each fish is uniquely patterned, making every individual one of a kind. Both sexes can express OB colouration, unlike most mbuna where it is typically female-limited.

The Red Zebra originates from the Metangula region of Mozambique in eastern Lake Malawi, where it inhabits exposed rocky shorelines at shallow depths. The OB morph arises from a naturally occurring genetic mutation that has been selectively propagated in captivity and is now widespread in the hobby.

In the aquarium, M. estherae OB is a hardy, colourful, and active species well suited to beginners working with mbuna for the first time. The striking OB pattern ensures this fish is always a focal point in any Malawi community. It is moderately aggressive and performs best in a mixed mbuna community with appropriate social structure.

Water: 24-28°C, pH 7.8-8.5, hard alkaline; robust species tolerating a range of stable conditions. Tank: 200L minimum; heavy rockwork; OB colouration is best displayed against a dark substrate. Feeding: Herbivore diet — spirulina pellets and Nori; the orange-red colouration intensifies with carotenoid-rich foods. Breeding: Maternal mouthbrooder; prolific breeder; OB gene passes to offspring; brood size 20-30. Compatibility: Moderately aggressive; excellent community mbuna; one of the easiest mbuna to keep successfully.
