长体拟丽鱼 · Elongate Mbuna

Overview

Slender-bodied Pseudotropheus elongatus is strongly territorial and aggressive. Females maintain feeding areas of their own, so social management extends beyond male rivalry.

Distribution & habitat

It is recorded from Mbamba Bay and Nkata Bay in Lake Malawi. Typical habitat is shallow and rocky, often with smaller stones and little accumulated sediment.

Aquarium setup

Use a tank starting around 120 by 38 by 30 cm, preferably larger. Arrange abundant shelters and caves over sand, retain some open areas, and allow algae to grow on the rocks. Cover is essential because an unreceptive female may be killed.

Diet & feeding

Emphasize vegetable ingredients such as spirulina foods, blanched greens, and nori. Add live or frozen foods for variety, while avoiding beef heart and other red meats.

Behaviour & compatibility

Avoid peaceful Malawian companions. Robust mbuna with different markings may be possible, but male conspecifics can be killed even in a large aquarium. Keep at least four to six females per male to distribute attention, with the ability to separate harassed individuals.

Sexual dimorphism

Mature males are usually larger and have brighter anal-fin egg spots.

Breeding

Use a dedicated group of one male and four to six females, around 25–26.5 °C and pH 8.2–8.5. The male courts forcefully at a cleaned site. Eggs are collected by the female and fertilized during her response to the anal-fin spots. Incubation lasts about three to four weeks without feeding. Brooding females often need protection from continued pursuit, although moving them risks stress-induced brood loss. Released fry accept brine shrimp nauplii and may receive maternal protection for several more days.

Notes

More than thirty forms have been recorded and should remain separate to avoid hybridization. Wild females leave their algae territories to spawn and then return carrying eggs; juveniles from earlier broods may defend the area during their absence.
