埃氏拟丽鱼 · Red Zebra

Overview

Color varies widely in Pseudotropheus estherae, and the familiar blue-male/orange-female pattern is not universal. This robust mbuna is relatively moderate within its group, but courtship pressure and a tendency to gain excess weight still require attention.

Distribution & habitat

It occurs along the Mozambican and Malawian shores of Lake Malawi, from the Metangula and Minos Reef area toward Gome. Rocky coasts and reefs form its habitat.

Aquarium setup

Start around 120 by 38 by 30 cm and favor a larger aquarium where possible. Provide extensive secure rockwork over sand, with open gaps and algae-covered surfaces for browsing.

Diet & feeding

Keep plant ingredients prominent, using spirulina-based foods and suitable greens with live or frozen supplements. Avoid rich meats such as beef heart. Prepared foods should be portioned carefully because obesity is a particular concern.

Behaviour & compatibility

Similarly sized mbuna are more suitable companions than peaceful peacocks or utaka. One male with several females is the more manageable arrangement; multiple males need a very large aquarium. Watch for persistent pursuit within any group.

Sexual dimorphism

Locality affects coloration: males may be blue, orange, or orange-blotched, and females can also vary. When both sexes share a color, larger size and more numerous, larger anal-fin egg spots favor identification as male.

Breeding

Maternal incubation is readily possible with one male and at least three females. Use about 25–26.5 °C and pH 8.2–8.5. The male prepares a flat surface or shallow pit; the female collects eggs and receives sperm while responding to his egg spots. She carries the brood for three to four weeks without eating. Disturbance can cause brood loss, and extended separation may affect her return to the social group. Fry take small live foods and fine prepared foods.

Notes

Keep geographic forms separate because they hybridize. In the absence of a male, a female may assume male-like coloration and court other females, without being able to fertilize eggs.
