Breeding Thysochromis ansorgii (Five-Banded Cichlid)

Thysochromis ansorgii is a pair-bonding West African cichlid that spawns on substrate, preferring caves. Both parents guard eggs and fry in soft, slightly acidic water.

Overview

Thysochromis ansorgii is a cichlid native to coastal basins of West and Central Africa, from Ivory Coast to Gabon. According to FishBase it is a pair-bonding, substrate brooder that spawns preferentially in caves or cave-like structures. It reaches around 8.8 cm SL and lives in soft, slightly acidic freshwater. These traits make it a manageable substrate-spawning subject for soft-water aquaria.

Conditioning

Maintain water within the species' documented range: temperature 24-26 °C, pH 6.0-8.0 and hardness around 5-19 dH (FishBase). Soft, slightly acidic water reflects the natural habitat and is associated with successful pairing. Condition prospective breeders on a varied omnivorous diet to bring them into spawning condition.

Breeding Setup

Because the species spawns preferentially in caves or cave-like structures (FishBase), the breeding tank should offer enclosed spawning sites such as flat-roofed shelters or inverted vessels. A pair holds and defends a territory around the chosen cave. Soft, acidic to neutral water within the parameters above supports spawning.

Spawning Behavior & Trigger

As a pair-bonding substrate brooder, the pair selects and cleans a spawning surface within or near the cave. In biparental substrate-spawning cichlids the female typically fans the eggs while the male guards the site from intruders, and after hatching both parents move the offspring and defend the swarm as it travels along the bottom (Tropical Fish Hobbyist). Substrate spawning with biparental care is regarded as the ancestral cichlid reproductive mode.

Egg & Fry Care

Eggs are deposited on the cleaned substrate and guarded by the pair. Once free-swimming, fry are herded as a school and defended by both parents. Newly free-swimming fry of small cichlids accept fine first foods such as freshly hatched brine shrimp and powdered fry preparations.

Common Challenges

Maintaining soft, slightly acidic water within the documented range is important for this West African species. Pair incompatibility and disturbance of the spawning cave can interrupt breeding; providing secure enclosed sites and stable parameters reduces failed attempts.
