Hemichromis stellifer Breeding Guide

Breeding the star-spangled jewel Hemichromis stellifer, a Congo-basin pair-bonding substrate spawner with biparental brood care.

Overview

Hemichromis stellifer is a jewel cichlid of the Congo basin, recorded from Equatorial Guinea to Cabinda, central Gabon, the western Republic of Congo and the Congo River from Pool Malebo to its estuary. FishBase gives a maximum standard length of 10 cm and lists it as a pair-bonding substrate brooder. It is a red, blue-spotted jewel with a carnivorous trophic level around 3.4.

Sexing

As a Hemichromis jewel cichlid the sexes are similar in pattern, and the most reliable approach is to grow on a group and let a pair form. Females in spawning condition fill out with eggs. As in related jewels, intensified red coloration accompanies breeding.

Conditioning

With a carnivorous trophic level, this jewel is conditioned on meaty live and frozen foods. Like other jewels it is an adaptable feeder, so a well-fed, settled pair readily reaches breeding condition.

Breeding Setup

FishBase records a temperature range of 22-26 C for the species in freshwater. Following the Hemichromis pattern, provide a tank with flat stones and cover so the pair can claim an open spawning surface and defend a territory around it.

Spawning Behavior & Trigger

FishBase classifies the species as a pair-bonding substrate brooder, meaning the bonded pair spawns onto a surface such as a flat stone rather than in a cave. As with related jewels, a securely bonded pair in stable warm water is the trigger for spawning.

Egg & Fry Care

Brood care follows the jewel pattern of biparental guarding, with both parents tending the eggs and then the free-swimming fry, which take small foods. In the well-documented related jewel Hemichromis lifalili the female is the main caregiver while the male helps once the eggs hatch, and parents lead the free-swimming fry around the territory. Specific egg counts and developmental timings for H. stellifer itself are not detailed in the consulted sources and so are omitted.

Common Challenges

Like other jewels, the species is aggressive when breeding, so the tank needs space and structure and tankmates should be robust. Because species-level breeding data is limited, keepers should plan for the general jewel-cichlid pattern of a defended spawning territory and biparental fry care.
