Nematobrycon palmeri is a mid sized species of tetra from Colombia which reaches about 2" long. Males have blue eyes, a triple forked tail and a purple-ish sheen over the body; females are more drab (but still gorgeous!) and have green eyes. These very peaceful tetras are the perfect addition for almost any community tank.
These are juveniles around 1" long of the selectively-bred black morph. Their whole body is a rich jet black, but they still retain their colourful eyes!
