This species is of typical elongated tetra appearance; it is of plain basic coloration but with two distinct, adjacent longitudinal stripes, white above black. The eye has two thin but distinctive colour bands across the top, red above yellow. Despite its common name, it does not particularly resemble the neon tetra, which belongs to a different genus.

Special Requirements - The Black Neon can be susceptible to pH and temperature fluctuations. Take care when acclimatising your new fish, adding small an amount of tank water to the bag every 10 minutes for an hour.

Tanks Mates and Compatibility – They tend to be timid and, because of their small size, should not be kept with large or aggressive fish which may bully or simply eat them. Fish that mix well in an aquarium are guppies, dwarf cichlids, smaller danionins and barbs, other types of tetras, such as the rummy-nose tetra, cardinal tetra, and glowlight tetra, and other community fish that live well in an ideal tetra water condition. These fish swim at the top level of the aquarium, and do not feed from the bottom of the tank. Therefore, it is recommended they be kept with bottom dwelling fish (such as Pygmy Corydoras) so that leftover food is then eaten up off the substrate and not left to waste.

Ideal Number to Keep – Mid-level feeders, they are best kept in schools of six or more, for the shoaling effect when they move around the tank. They shoal naturally in the wild and are thus more brightly coloured and more active when kept as a shoal as opposed to singly.

Feeding – Tetras are omnivores and will accept most flake foods, if sufficiently small, but should also have some small foods such as brine shrimp, daphnia, freeze-dried bloodworms, tubifex, which can be stuck to the side of the aquarium, and micro pellet food to supplement their diets. Some frozen foods, including frozen blood worms, add variety to their diets.
