The neon tetra is a freshwater fish of the tetra fish family. Neon tetras have vibrant blue bodies with striking red markings from the belly to the tail.
Because of their hardiness, neon tetras have low care needs, making the fish a popular choice for beginner fishkeepers.
There are several variations of neon tetras available, including black neon tetra and diamond head neon tetras.
Neon tetras are found in the northern and western Amazon basins in Peru, Brazil, and Colombia. The waters in this region are acidic, with a pH as low as 0.4. Neon tetras live in blackwater and clearwater streams.
The neon tetra’s natural habitat is declining due to deforestation and farming, but there are still a lot of neon tetras in the wild. More than 1.5 million neon tetras are imported from fish farms to the U.S. every month.
