The Guyana fin-eater tetra (Roeboexodon guyanensis) is a freshwater fish of the family Characidae that grows up to 12 cm.
Description
The Guyana fin-eater tetra is a South American characin of the family Characidae from the Guianas. The species grows to about 12 cm and has a slender, silvery body. It is relatively rare and occurs in creeks with fast-flowing water over a sandy bottom. Notable is its dentition: the particular form of its teeth is adapted to a diet in which the fish can nip pieces from the fins and scales of other fishes, a form of scale- and fin-eating. As a fast hunter it often stays in flowing water. Owing to its modest size the species is of limited fishery interest. It is harmless to humans.
