Comments: This tetra is olive-green on the dorsal surface and silvery on the belly. There is an iridescent, pale green-blue line along the flanks which looks great, from the top of the eye to the caudal peduncle. Below this is a dark area gradually pales towards the lower part of the body. Fins are mostly colourless, and an adipose fin is present.
