Care
The Onespot Catfish is known from the Chiloango, Congo, Kasai, and Ubangi River basins. The aquarium should be spacious (at least 4ft long for juveniles) with a soft sandy substrate in order to protect the long sensory barbels. It should be decorated with a good amount of bogwood, rocky caves/PVC tubes, and robust planting to provide shady areas, but you should also ensure that a roomy swimming space is left along the front of the tank. External canister filtration is recommended, as these fish are voracious eaters and can produce a fair amount of waste. The water should be well-oxygenated with a moderate current, and frequent partial water changes are a must to help keep nitrate to a minimum. These fish are most comfortable in aquaria with subdued lighting, and the use of blue-moon type illumination is highly recommended so that you may observe a few hours of the nightly goings-on in an aquarium containing these catfish. Although territorial aggression tends to increase slightly as the fish mature, more than one may be kept together providing that there is an abundance of hiding places and visual barriers within the tank. Ensure that heaters are covered with heater guards to prevent these catfish from being burned when looking for dark crevices to rest against. Companions should be peaceful and larger than 5cm (2") in length (otherwise they may be predated upon); good tankmates could include some of the medium sized tetras, barbs, gouramis, knifefish, large loricariids, rainbowfish, or some of the robust West African cichlid species. Most specimens have a single large dark spot on each side of the silver coloured body, but there are aberrant individuals with no spots, more than one spot and some with a differing number of spots on each side. May also be seen on sale as the Onespot Squeaker.
Feeding
Omnivorous. Offer a variety meaty frozen foods such as bloodworm, white mosquito larvae, vitamin-enriched brineshrimp, Mysis shrimp etc., along with some sinking catfish pellets/tablets/granules. Be sure to offer some vegetable matter such as cucumber, courgette, and shelled peas, along with occasional algae wafers. These are greedy fish, and are a little susceptible to bloating so take care not to overfeed, and go easy on the amount of dried foods given - avoiding all floating foods.
Breeding
This species has not been bred in the home aquarium. In the wild, these egg scatterers form distinct pairs when breeding, but exhibit no parental care.
