Comments: Occurs in clear, flowing streams, as well as in still water.  Found in well-vegetated stream and lake margins.  Forms moderate-sized shoals, swimming just below the surface (Ref. 44894).  Feeds on insects and their larvae, small crustaceans, snails and some algae.  Although attractive, they are delicate and usually difficult to maintain in captivity (Ref. 44894).
