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.
