Yellow-tailed African tetra

The yellow-tailed African tetra (Alestopetersius caudalis) is a freshwater fish that lives in the Congo River basin. It is found in both the Democratic Republic of the Congo and the Republic of the Congo (via an unsubtantiated report). It is an omnivore in the wild, but seems to have little difficulty in adjusting to normal aquarium foods. The species can tolerate water up to 20 degrees DH, though it does better in softer water. A temperature of 22–26° C (72–79° F) and a pH of between 6.5 and 7.5 is suitable.
