Feeding

Accepts dry food
Accepts frozen
Requires live food

Herbivore-leaning omnivore. Spirulina flake and pellets as the staple. Blanched vegetables (peas, zucchini, spinach) and nori as supplements. Frozen brine shrimp and mysis occasionally. Avoid bloodworm (bloat risk). Feed 2-3 times daily in small amounts. The orange coloring benefits from food containing astaxanthin or other carotenoid pigments.

Compatibility

  • Moderately aggressive Mbuna that's slightly calmer than demasoni and Melanochromis species but still too aggressive for a standard community tank. Keep with other Mbuna of comparable size and temperament.
  • Standard Mbuna stocking: 1 male to 3-4 females in a group of 8-12. Overstocking with rock cover to break sightlines. One male dominates and the females establish their own pecking order.
  • Despite the common name, the most popular color morph is solid orange. The "zebra" in the name refers to the original description of the species which included barred morphs. Stores often sell orange, red-orange, and albino variants all as "red zebra."
  • Hybridizes with other Metriaclima/Maylandia species, so avoid keeping with closely related species if purity matters.

Origin and habitat

Endemic to Lake Malawi, found along the eastern coast from Chilucha Reef near Metangula southward to Narungu, with the highest concentrations around Minos Reef. The range extends into both Mozambican and Malawian waters. Described by Konings in 1995 as Pseudotropheus estherae; subsequently placed in Metriaclima, now in Maylandia, though the correct genus remains debated in the cichlid community. The species is polymorphic: normal wild females are beige to brown, while males are typically bright blue. Red-orange females (O morph) and blotched females (OB morph) occur at certain localities; O morph males, which are white-pink with blue-tinged fins, are found only at Minos Reef. In the aquarium trade, the orange morph has been preferentially bred and is now the dominant form sold in stores. Females grow to about 10 cm; males to about 12.7 cm. Territorial and aggressive, particularly toward similar-looking zebra-type species; should not be kept with Maylandia callainos or Labidochromis caeruleus as they can hybridize. Maternal mouthbrooder; females hold fertilized eggs and fry for about 21 days. Described as "mid-tempered" among mbuna, but still aggressive enough that care is needed in community setups.

Breeding

Maternal mouthbrooder. The male establishes a territory on a flat rock and courts passing females with lateral displays and quivering. Spawning follows the standard Mbuna egg-spot mechanism. Clutch size is 15-30 eggs. Female incubates for 18-21 days. Fry are released at about 1012 mm and immediately eat crushed flake and spirulina. In a Mbuna community tank, some fry survive in rock crevices. Red zebras are prolific breeders; a healthy group produces new broods continuously.

Common problems

Malawi bloat, the universal Mbuna concern. Prevention through diet and water quality is far more effective than treatment. Aggression management through proper stocking density. Hybridization with other Metriaclima species produces offspring that are difficult to identify and trade. The color morph confusion means keepers sometimes get a mix of orange, blue, and OB (orange-blotch) fish sold as "red zebra" that may be hybrids or different species entirely. If purity matters, buy from a specialized cichlid breeder rather than a general fish store.

moderately heavy for its size; mbuna eat constantly and produce waste to match. See the methodology page for the formula.
