Breeding Telmatochromis vittatus

How to breed the Striped Telmatochromis (Telmatochromis vittatus): a secretive bi-parental cave spawner from Lake Tanganyika that pairs for life.

Overview

Telmatochromis vittatus is a small Lamprologine cichlid endemic to Lake Tanganyika, reaching a maximum standard length of about 8.5 cm. It is a bi-parental cave spawner: pairs form naturally and, according to Seriously Fish, tend to remain together for life. Spawning is secretive, so a clutch is often noticed only once free-swimming fry appear.

Sexing

The species is not easy to sex. Adult males tend to be slightly larger than females and have a more slender shape; otherwise external differences are subtle, and reliable pairing usually comes from observing bonded behaviour rather than appearance.

Conditioning

Condition adults on a carnivorous diet appropriate to the species. Stable hard, alkaline water encourages spawning readiness. For breeding, Seriously Fish recommends a pH of 8.2-9.0 and a temperature of roughly 25-27 C (77-80 F).

Breeding Setup

Provide an aquarium of at least 75 cm (30 in) in length with sand substrate and numerous rock caves or empty shells. Tight crevices and shells where the pair can retreat and defend a brood are essential, since this fish is territorial and somewhat shy.

Spawning Behavior & Trigger

Courtship is vigorous and easy to miss. The female deposits adhesive eggs on the wall or roof of a cave or shell. Stable mature water and the presence of a suitable cave act as the principal triggers; a settled, bonded pair will spawn repeatedly within their territory.

Egg & Fry Care

The female remains in the cave tending the eggs while the male guards the surrounding area. Brood care is short-lived: the adults lose interest once the fry are free swimming, roughly two weeks after spawning. At that stage the fry are large enough to accept brine shrimp nauplii, microworm or powdered dry foods.

Common Challenges

Because care ends early, free-swimming fry are best protected by moving them or removing the parents once independence is reached. The secretive spawning style means broods can be lost before they are noticed if predatory tankmates share the aquarium.
