Red Fin Penguin Tetra (Thayeria sp. Red Fin Penguin)

The Red Fin Penguin Tetra is a recently discovered relative of the common Penguin Tetra found in the Teles Pires drainages of Brazil. With their distinctive horizontal band and bright red caudal fin, peaceful, schooling nature, the Red Fin Penguin Tetra is deservedly popular in the aquarium hobby. In the wild, they inhabit slow moving, warm, acidic streams but will adapt to a wide range of conditions in the aquarium. Like most of their close relatives, they are a loosely schooling species that will do best in groups of 5 or more and will get along well with most similarly sized, peaceful tankmates. Subdued lighting, plenty of cover in the form of driftwood or plants, and slightly soft water will help promote vibrant coloration.
