Issue
Myers did not originally illustrate this fish but Géry (1977:147) published a drawing by Pablo Bravo prepared under Myers’ direction, probably from the holotype. Until rather recently it was not known except for the preserved types. It occurs in acid clear and black water streams and is collected with the green neon, Paracheirodon simulans, and imported with it at times. It is a very slender fish, and the dorsal fin is placed far back on the body, almost over the anal fin. In life it grows to 6 cm or more. Its breeding behavior has not been noted.
