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.
Aulonocara gertrudae is a species of haplochromine cichlid which is endemic to Lake Malawi, being found in Malawi, Mozambique, and Tanzania. The habitat varies between populations, those south of the Ruhuhu River are sand dwellers which exploit the sandy muddy substrates found near river mouths, while those to the north of the Ruhuhu will occupy rocky habitats too. This is thought to be cause there are fewer rock inhabiting congeners north of the Ruhuhu. The territorial males of this species excavate a burrow in the sand or they may use a cavity formed in a rocky area, especially in the northern populations. The females are found in small foraging groups in the vicinity of the males. The specific name honours Konings' wife, Gertrude Dubin.
Betta chini is a species of gourami endemic to the island Borneo where it is only known from the Malaysian state of Sabah. It inhabits very shallow waters of peat swamps.

This species was formally described in 1939 as Anabas damasi by the Belgian ichthyologist Max Poll, the type locality given was Semliki River at Ishango in the Democratic Republic of Congo. The type was collected by Hubert Damas (1910-1964) of the University of Liège and when he described the species Poll named Damas as co-author, this meant that Damas was the co-author of a specific name which honoured himself.

Parablennius sierraensis is a species of combtooth blenny found in the Eastern and Central Atlantic: Cape Verde and the Gambia to Namibe, Angola. The species name refers to Sierra Leone, the type location. However, the IUCN give the southern limit of the distribution as being Sierra Leone.
Acanthanectes hystrix is a species of triplefin blenny. It was described by Holleman and Buxton in 1993. So far the species has only been recorded in the waters off Tsitsikamma National Park in the Eastern Cape, South Africa but its distribution is probably more extensive, although it is likely to endemic to South Africa. It is a demersal species which is found below the low water mark on rocky reefs with microalgae at depths of 10 to 24 metres. Their eggs hemispherical in shape and are coated with many sticky threads which fix them among the algae at the nesting sites. The larvae are planktonic and have mainly been recorded from shallow, inshore areas. The specific name hystrix means porcupine and refers to the spiny appearance of this fish.

Walter is honoured in the specific name of another species they discovered, Betta foerschi.

This species can reach a length of 20 centimetres (7.9 in) SL. It is a commercially important species and is also found in the aquarium trade. This species was formally described by Georges Cuvier in 1831 with the type locality of Java. The collector of the type was collected in 1820 by the Dutch physician and biologist Johan Coenraad van Hasselt (1797-1823), whom Cuvier honoured in its specific name, with his friend Heinrich Kuhl.
