‘Chocolate Neon Tetra’
These fish were similar in look and behavior to H. herbertaxelrodi but they are slightly more colorful and have more interesting fins.
This is also one of the species that reproduced freely in a spawn-filled tank without any intervention from me. Quite a few fry grew up in that tank despite it containing adult vilmae as well as a school of cardinal tetras and a group of Hyphessobrycon roseus.
