费氏拟丽鱼 · Goldbreast Zebra

Overview

A large and highly aggressive mbuna, Pseudotropheus fainzilberi demands substantial space and careful social management. Its specialized grazing dentition includes additional rows extending farther into the mouth.

Distribution & habitat

The recorded range runs from Chirwa Island toward Usisya along the lake’s northeastern coast. It uses rocky shoreline and island habitat in Lake Malawi.

Aquarium setup

Treat about 120 by 45 by 38 cm as only a minimum starting point. Provide sand and extensive stable rockwork with caves, sheltered routes, and small open areas. Allow algae to remain for browsing.

Diet & feeding

Make vegetable ingredients the basis of the diet, with spirulina foods, greens, and nori supplemented by live or frozen items. Avoid rich, meat-heavy feeding such as beef heart.

Behaviour & compatibility

Avoid mild Malawian species. Other large, robust mbuna with different markings may be considered. Rival males can be killed even in large tanks, and unreceptive females are also at risk. Several females per male and abundant shelter help distribute attention but do not eliminate danger.

Sexual dimorphism

Males are usually larger and more colorful. Both sexes have anal-fin egg spots, but those of males are larger and more intense.

Breeding

A breeding group of one male and four to six females is preferable. Provide flat stones and open substrate around 25–26.5 °C and pH 8.2–8.5. The female collects eggs and receives sperm during interaction with the male’s anal-fin spots. She incubates for roughly three to four weeks without feeding. Continued male pursuit often makes separation desirable, but moving her risks brood loss from stress. Released young can take brine shrimp nauplii.
