Description: A long and slender fish with a forked caudal fin which can be mistaken for Pareutropius debauwi. The base color of the body is silvery. Underneath the black stripe along the lateral line and through the tail fin, there is a second black stipe which is interrupted around the anus. The caudal fin lobes have black tips, which are rounded. The adipose fin is transparent. Under poor water conditions the animals stay hidden or move around the bottom.

Female has a larger, more rounded stomach, however this only applies to well acclimated individuals. Pareutropius buffei is not often bred in aquaria, but it is possible. Breeding has been successful at 22-26 °C. The setup should consist of 2 males and 1 female. Usually during the morning hours about 100 white eggs are scattered among the plants. Remove the parents. The larvae hatch after 3 days and can be fed newly hatched Artemia nauplii. The young are fast growing.
