Tricky to visually sex. Mature females may be slightly plumper than males.

Tank compatibility

A peaceful fish, keep in groups of 6 or more. Will co-exist with most other peaceful community fish but avoid keeping them with slow-moving long-finned fish or fish that are large enough to eat it.


Omnivorous, should take pellets and flake as well as live and frozen food.

Feeding regime

Feed once or twice a day.

Environment Specifics

This fish prefers a spacious tank with open swimming place and room to shoal. Some hiding places in plants would be appreciated. They do require very soft, acidic and tannin-stained waters, they may be able to be carefully acclimated to slightly harder water.


A peaceful shoaling fish.


A pretty and distinctive tetra with red adipose, dorsal and anal fins along with red and white bands and a triangular black spot at the base of the caudal fin. The body is iridescent silver with a white band running along the spine from the dorsal spine to the caudal peduncle. Can be mistaken for Hyphessobrycon heliacus, but H.heliacus lack the red fins.
