Species: Hyphessobrycon herbertaxelrodi

Size: 4.5cm (1 three quarter inch)

Habitat: Streams and rivers in the Mato Grosso region of Brazil

Remarks: Soft, acid water will bring out this fish’s colours.

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. Females generally have deeper bodies and increase in girth at spawning times.
