Chilochromis duponti is a species of cichlid endemic to riverine habitats in the Chiloango River basin of Cabinda Province of Angola and the Democratic Republic of the Congo, the Kouilou-Niari River and lower Loeme River in the Republic of Congo, and the Nyanga basin and upper Ngounie River which is part of the Ogooué system in Gabon. The main part of its diet is aquatic vegetation, largely algae, but small amounts of invertebrates are eaten. It is spawns on to the substrate. This species reaches a length of 30 centimetres (12 in) SL. It is the only currently known member of its genus. The specific name honours the Édouard Dupont (1841-1911), a Belgian geologist who was a pioneer of the geological exploration of the Congo Basin and a director of the Brussels Museum.
Microctenopoma ansorgii is a small freshwater fish, known in the aquarium trade as the ornate ctenopoma, orange ctenopoma, ornate climbing perch, pretty ctenopoma, or rainbow ctenopoma. It is related to the more familiar spotted climbing perch, but looks very different. Its body is more elongated and rounded, with fins with red and black stripes; the color intensifies when the fish are displaying, with black bars becoming visible on the body. The ornate ctenopoma spawns at night, laying its eggs on a floating bubble nest like its relatives in the osphronemidae. It lives in the slow-flowing forest streams of the Congo Basin, where it feeds on worms, insect larvae, and other aquatic invertebrates. It is the most common member of its genus in the aquarium trade, where it is known for being a shy, easily bullied fish that needs live or frozen foods and which benefits from the presence of smaller dither fish to encourage it to come out of hiding.
The mesh-scaled topminnow is a species of fish in the family Poeciliidae. The two population groups are a southern group of populations found in Angola, Botswana, the Republic of the Congo, Malawi, Mozambique, and Zambia and a northern population group found in Chad, the Central African Republic, the White Nile in South Sudan and Sudan and in the northern Democratic Republic of Congo.

This species was described by George Albert Boulenger as Haplochilus hutereaui in 1913 with the type locality being Dungu on the upper Uelé River in the Democratic Republic of Congo. Boulenger received the type from Armand Hutereau (1875-1914), who was the head of a Belgian ethnographic expedition to the Congo, so he honoured Hutereau in the specific name.
