Care and Environment

Proper care for Robert’s catfish involves attention to tank size, water parameters, and habitat setup. A minimum tank size of 113 liters (30 gallons) is recommended to provide adequate space for swimming along the substrate. The ideal water temperature ranges between 23–27°C (73.4–80.6°F), with a pH of 6.2–7.5 and water hardness between 12–24°N (214.29–428.57 ppm). Efficient filtration is crucial to maintain high water quality, as this species is sensitive to changes. Regular water changes of at least 10% weekly are advised.

What type of substrate is best for Robert’s catfish?

A fine sand or smooth gravel substrate is ideal to prevent damage to their sensitive barbels.

Are there specific decorations that benefit Robert’s catfish?

Incorporating hiding places such as caves, driftwood, and plants can help them feel secure and reduce stress.

Feeding should consist of a balanced diet, including quality commercial flake or small pellets, supplemented with blanched vegetables like peas or cucumber. Occasional treats of live or frozen foods such as brine shrimp or bloodworms can be offered once or twice a week. Ensure any uneaten food is removed promptly to maintain water quality.

How often should Robert’s catfish be fed?

They should be fed daily, with portion sizes they can consume within a few minutes to prevent overfeeding.

Origin and Habitat

Robert’s catfish is endemic to the Democratic Republic of the Congo, specifically known from the Lukenie River. In the wild, they inhabit freshwater environments, often found in river systems with moderate flow. These habitats typically feature soft substrates and ample hiding spots among rocks and submerged vegetation, providing a natural refuge from predators and strong currents.

What type of water bodies do Robert’s catfish inhabit?

They are found in freshwater rivers with moderate flow and abundant hiding places.

Are there seasonal variations in their natural habitat?

Specific seasonal variations are not well-documented, but like many riverine species, they may experience changes in water flow and temperature.

Temperament and Compatibility

Robert’s catfish are known for their peaceful nature, making them suitable for community aquariums. They are bottom dwellers and prefer to stay near the substrate, often seeking shelter in caves or under driftwood. While they can be kept singly, they may exhibit more natural behaviors when housed with other peaceful species.

Can Robert’s catfish be kept with other bottom dwellers?

Yes, they can coexist with other peaceful bottom dwellers, provided there is enough space and hiding spots to prevent territorial disputes.

Are they suitable for a community tank?

Absolutely, their peaceful temperament makes them excellent candidates for community tanks with other non-aggressive species.

Interesting Facts

Robert’s catfish is part of the Mochokidae family, commonly known as upside-down catfish, though this particular species does not exhibit the upside-down swimming behavior. They possess three pairs of barbels, which are sensitive, whisker-like structures used to detect food in the substrate. Additionally, their unique coloration and patterns provide effective camouflage in their natural habitat, helping them evade predators.

Do Robert’s catfish swim upside down like some of their relatives?

No, unlike some members of the Mochokidae family, Robert’s catfish do not exhibit upside-down swimming behavior.

What role do their barbels play?

The barbels are sensory organs that help them locate food in the substrate.
