Gulf's White Convict Fish, (Cichlasoma facetum) — 4-5cm

Overview

The Gulf's White Convict Fish (Cichlasoma facetum, now correctly known as Australoheros facetus) is commonly known as the chameleon cichlid or chanchito. This adaptable South American species is native to northern Argentina, Paraguay, Uruguay, and southern Brazil, where it inhabits temperate to subtropical freshwater environments. Available as tropical fish for sale UK, this species represents one of the more cold-tolerant cichlids in the hobby, capable of thriving in cooler water temperatures than most tropical fish. The "white convict" appearance comes from its pale body coloration with dark vertical barring, resembling the more commonly known convict cichlid from Central America. For aquarists seeking a hardy, interesting cichlid that tolerates a wide range of conditions, Australoheros facetus offers robust health and engaging behavior.

Appearance

Australoheros facetus displays a pale grey or white body with dark vertical bars, giving it the "white convict" common name. The body is robust and laterally compressed, with a slightly pointed snout and large, expressive eyes. Coloration can vary significantly with mood, stress level, and breeding condition—hence the alternative common name "chameleon cichlid." Males are larger and develop more intense coloration and a slight nuchal hump as they mature. Breeding pairs intensify their patterning, with both sexes showing striking contrast between the pale body and dark bars. The overall appearance is understated yet attractive, with the fish's color-changing ability adding visual interest.

Natural Habitat

Native to temperate and subtropical regions of South America—northern Argentina, Paraguay, Uruguay, and southern Brazil—Australoheros facetus inhabits rivers, streams, and lakes with muddy or sandy substrates. These habitats experience seasonal temperature variations, and the species has evolved to tolerate cooler water than most tropical cichlids. The water is typically neutral to slightly alkaline, moderately hard, and well-oxygenated. The environment provides ample cover in the form of rocks, roots, and aquatic vegetation.

Aquarium Setup

Provide a spacious aquarium with excellent filtration and regular water changes. Use a sand or fine gravel substrate with robust rockwork and driftwood to create caves and visual barriers. This species is adaptable and can tolerate a wide range of water parameters, making it suitable for temperate or tropical setups. Plants should be robust or potted, as cichlids may dig or rearrange decor. A minimum tank size of 200 litres is recommended for a pair or small group. Strong filtration and regular maintenance are essential for optimal health.

Feeding

Australoheros facetus is omnivorous and accepts a wide variety of foods. Offer quality cichlid pellets as the staple, supplemented with frozen or live foods such as bloodworms, brine shrimp, and earthworms, plus vegetable matter such as spirulina flakes or blanched vegetables. Feed moderate portions once or twice daily. This species is undemanding in terms of diet and will thrive on a varied, balanced feeding regimen.

Behaviour and Temperament

Australoheros facetus is semi-aggressive to aggressive, with territorial behavior intensifying during breeding. Males defend territories vigorously, and pairs become highly protective of eggs and fry. Despite their aggressive reputation, they can coexist with appropriately sized and robust tankmates in spacious aquariums. This species is intelligent and interactive, often recognizing their keepers and displaying interesting social behaviors.

Tank Mates

House with other robust South American cichlids of similar size and temperament, large catfish, and sturdy community fish that can tolerate semi-aggressive tankmates. Avoid small fish, delicate species, slow-moving or long-finned fish, and peaceful community fish. Breeding pairs are best kept alone, as parental aggression can be extreme.

Breeding

Australoheros facetus forms monogamous pairs and spawns on flat surfaces or in caves. Both parents guard the eggs and fry with dedication, becoming highly territorial. Eggs hatch in approximately three days, and fry become free-swimming several days later. Fry are large enough to accept newly hatched brine shrimp immediately. Breeding is relatively straightforward with this hardy species, making it suitable for aquarists new to cichlid breeding.
