The neon tetra has a light-blue back over a silver-white abdomen. The fish is characterized by an iridescent blue horizontal stripe along each side of the fish from its nose to the base of the adipose fin, and an iridescent red stripe that begins at the middle of the body and extends posteriorly to the base of the caudal fin. Rarely, they develop a dark olive-green sheen lining on their backs. The fish is partially transparent (including fins) except for these markings. During the night, the blue and red become gray or black as the fish rests—it reactivates once it becomes active in the morning.

Special Requirements - It is best to provide your Neons with a mixed environment with some open swimming space and some plant cover.

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. 

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 - Neon 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. A tropical sinking pellet is ideal, as most brands of these include natural colour enhancers that bring out the colour in neon tetras. Some frozen foods, including frozen blood worms, add variety to their diets.
