Chocolate Talking Catfish Care Guide - Aquarium Setup, Diet & Breeding

Chocolate Talking Catfish are robust, dark-bodied members of the doradid family, with a broad head, small eyes and rows of bony plates along the sides. Their brown to chocolate colouring is often marked with darker and lighter patterning, helping them blend into shadowed river-bottom habitats. The sharp-looking scutes and strong pectoral spines give this catfish an armoured appearance.

This is a nocturnal and retiring species that spends much of the daylight hours tucked beneath wood, among leaf litter or inside a cave. After dark it becomes more active, exploring the bottom with its barbels and searching for food. Although generally peaceful, it can make a surprisingly audible grunting or clicking sound when stressed or handled, produced by rubbing parts of its body and fin structures together.

In nature, Chocolate Talking Catfish are associated with soft, often tannin-stained waters and sheltered areas where submerged roots, branches and debris provide cover. Their underside-oriented lifestyle and sensitive barbels are well suited to locating food in dim water and loose river sediments.

They are peaceful, fascinating community fish for aquarists who enjoy observing nocturnal behaviour rather than constant daytime activity. Several individuals may rest together in a shared refuge, gradually becoming more confident as they settle into a suitable aquarium.

Chocolate Talking Catfish are native to tropical South America, with records from the Amazon, Orinoco and related river systems in countries including Brazil, Peru, Colombia and Venezuela. They inhabit slow-moving tributaries, flooded forest waterways and other sheltered freshwater habitats.

A group should have at least a 120-litre aquarium, with a footprint of roughly 90 by 40 cm or larger; more floor space is preferable as the fish mature. Use smooth fine sand or rounded gravel that will not damage their barbels, together with driftwood, caves, sturdy plants and shaded areas for daytime shelter. Gentle to moderate water movement, good filtration and regular maintenance suit them, while subdued lighting and leaf litter can help recreate their naturally sheltered environment. Keep the aquarium tightly covered because these catfish may escape, particularly when startled.

Up to about 12 cm (4.7 inches) in standard length, with females often reaching around 12 cm and males usually remaining slightly smaller at approximately 10–11 cm (3.9–4.3 inches).

This omnivorous bottom-feeder accepts sinking catfish pellets, wafers and granules, supplemented with frozen or live foods such as bloodworm, blackworm, brine shrimp, chopped prawns and other small aquatic invertebrates. Feed after the aquarium lights dim so the food reaches them before faster daytime fish consume it. Occasional soft vegetable matter may also be accepted, but a varied diet with a strong meaty component is most suitable.

Chocolate Talking Catfish are peaceful and can be kept with similarly peaceful South American community fish, including larger tetras, peaceful rasboras, pencilfish, peaceful barbs, angelfish, dwarf cichlids and other non-aggressive catfish. They should not be housed with large predatory cichlids, aggressive territorial fish or species small enough to be swallowed. Avoid keeping them with boisterous bottom-dwellers that constantly compete for hiding places, and take care when using nets because their fin spines can become snagged.

Chocolate Talking Catfish are rarely bred in ordinary home aquariums. They are cave-spawning fish, so a mature group can be offered several tubes, caves or upturned pots with clean, well-oxygenated water and a diet rich in meaty foods. The female deposits eggs inside a sheltered cavity, where they are fertilised by the male; the parents should be removed or the eggs transferred to a separate rearing tank because the adults may eat the spawn. Fry can be raised on newly hatched brine shrimp and other suitably tiny foods. Captive spawning may be encouraged by a large, slightly cooler, well-filtered water change that imitates seasonal rainfall.

Sexual differences are subtle. Mature females are generally broader through the body, particularly when carrying eggs, while males tend to be slimmer; colour and armour pattern are not reliable ways to sex them.
