Ornate ctenopoma (Ctenopoma ansorgei) — 3-4cm

Overview

Ornate Ctenopoma (Ctenopoma ansorgei), also known as the Ornate Climbing Perch or Rainbow Ctenopoma, is a beautifully patterned, shy African labyrinth fish that adds color and character to a calm, well-covered aquarium. Native to Central Africa, especially the Congo River basin and surrounding slow-moving freshwater habitats, this species is prized for its intricate markings, peaceful nature, and fascinating air-breathing behavior. Now available for sale UK from Tropical Fish Co, this unusual labyrinth fish is ideal for the specialist community aquarium keeper.

Appearance

The Ornate Ctenopoma typically reaches around 3.5 cm in total length (though some sources report larger sizes in optimal conditions), making it a small labyrinth fish. The body is laterally compressed and robust, with an intricate pattern of orange, red, blue, and black markings that give the species its "ornate" common name. The fins are elaborate and flowing, often showing vivid coloration in well-conditioned males. Females are generally less colorful. Healthy specimens have bright, clear eyes and smooth, undamaged scales.

Natural Habitat

In the wild, Ctenopoma ansorgei is native to Central Africa, especially the Congo River basin and surrounding slow-moving freshwater habitats. These waters are typically soft, warm, and slightly acidic, with muddy or sandy substrates and dense aquatic vegetation providing cover. Light levels are low due to the forest canopy and tannin-stained water. The fish spend much of their time among plants and leaf litter, feeding on small invertebrates and using their labyrinth organ to breathe atmospheric air.

Aquarium Setup

A well-planted aquarium of at least 40 litres is recommended for a pair or small group of Ornate Ctenopomas. Use a fine, dark substrate and incorporate plenty of live plants such as Java moss, Java fern, Cryptocoryne species, and floating plants to provide cover and subdued lighting. Add driftwood and dried leaves to replicate the tannin-rich waters of their natural habitat. Filtration should be gentle, and lighting should be subdued. A tightly fitting lid is essential, as labyrinth fish can jump and breathe atmospheric air.

Feeding

The Ornate Ctenopoma is a carnivore and thrives on a varied meaty diet. Offer live or frozen foods such as bloodworms, brine shrimp, daphnia, mosquito larvae, and small insect larvae daily. Many individuals can be trained to accept quality carnivore pellets or prepared foods. Feed once or twice daily in small amounts to maintain excellent water quality.

Behaviour

This labyrinth fish is semi-aggressive, shy, and best kept in pairs or small groups in a suitably sized aquarium. They spend much of their time hiding among plants and cover, and are most active during dawn and dusk. Males may engage in territorial displays, but serious aggression is rare if provided with plenty of hiding places. Due to their shy nature, they may be stressed by bright light or constant activity.

Tank Mates

The Ornate Ctenopoma is suitable for a peaceful community aquarium with other small fish. Good tankmates include peaceful fish of similar size that will not fit in its mouth, small to medium tetras, peaceful rasboras, and peaceful bottom dwellers of similar size. Avoid very small fish that can be swallowed, fin-nipping species, highly aggressive cichlids, hyperactive boisterous fish, and other small labyrinth fish kept in cramped quarters.

Breeding

Breeding the Ornate Ctenopoma is uncommon in home aquaria. A well-conditioned pair may spawn in dense cover. The male typically guards the nest and eggs, and fry should be offered very small live foods once free-swimming.
