Neon tetras originated from the clear water and blackwater streams and tributaries in the Orinoco and Amazon basin in Brazil, Columbia, and Peru. These are regions of blackwaters beneath dense forest canopies that allow very little light to get through. Neon tetras live in shoals mainly in the middle water layers and feed on worms and small crustaceans.
The neon tetra has a slender torpedo-shaped body that reaches no more than 4cm in length. What this fish lacks in size, it makes up for in colour. From the tip of its nose to the adipose fin, the neon tetra has a bright neon blue stripe. It is believed this bright stripe makes them more readily visible to each other in blackwater conditions.
Like other colourful fish, the bright colors of the neon tetra will fade at night when it is resting, if it becomes alarmed, or when it is ill.
Always keep neon tetras in schools of at least 6 or more.
Neon tetras do well in a community tank as long as tankmates are not large or aggressive. Small peaceful fish such as rasboras, small tetras, dwarf gouramis, as well as corys and other small catfish are good choices as companions. Avoid larger tetras, as they will eat neon tetras at the first opportunity. The rule of thumb is, if the mouth of the fish opens large enough to swallow the neon, they will do it sooner or later.
Neon tetras are omnivores, meaning they will eat a variety of foods. Fine flake food, small granules, live or frozen brine shrimp or daphnia, and frozen or freeze-dried bloodworms are all good food choices. Offer a variety of food to ensure good health.
