Astatotilapia latifasciata Breeding Guide

Breeding Astatotilapia latifasciata (Zebra Obliquidens), a hardy, prolific maternal mouthbrooder from Uganda's Lake Kyoga system.

Overview

Astatotilapia latifasciata, widely sold as Zebra Obliquidens, is a robust Victorian-region haplochromine endemic to Lake Kyoga and the much smaller neighbouring Lake Nawampasa in central Uganda. It reaches about 12.5 cm. The species is a prolific maternal mouthbrooder and one of the more readily bred African haps, though it is reported as critically endangered in the wild while common in captivity.

Sexing

Males are slightly larger and more colourful, showing a bright yellow body with broad black bars and red finnage, and they bear egg-shaped spots on the anal fin. Females are duller. A varied diet including shrimp and krill helps intensify male coloration.

Conditioning

Feed a varied omnivore diet to bring females into condition; protein-rich foods such as shrimp, krill and insect larvae support male colour and female egg development. Stable hard, alkaline water keeps the colony in spawning condition.

Breeding Setup

Breed in a species tank as a harem of roughly one male to four females (at least three), in an aquarium of about 48 inches (120 cm) aquascaped with rocky outcrops and areas of sand to serve as spawning sites; hardy plants such as Anubias or Vallisneria can be added. The wide male-to-female ratio spreads out courtship aggression.

Spawning Behavior & Trigger

The male holds a territory and displays to attract a ripe female. The female lays eggs and collects them into her mouth; the male's anal-fin egg spots prompt the collecting behaviour, during which fertilisation occurs orally. Spawning is maternal mouthbrooding.

Egg & Fry Care

Females usually lay 20–60 eggs depending on size. The fry hatch in about 8 days and become free-swimming by around day 20. Released fry accept brine shrimp nauplii, daphnia or crushed flake, and the mother protects them once free-swimming; isolating a holding female improves survival.

Common Challenges

Keep a single male per tank to control courtship aggression. Because look-alike Victorian-region species are common in the trade, keep this species apart from similar yellow-and-black haps to avoid hybridisation, and maintain its captive line carefully given its endangered status in the wild.
