Neon Tetra

The Neon Tetra (Paracheirodon innesi) is one of the most widely kept and universally beloved freshwater tropical fish in the world. Native to the blackwater and clearwater streams of the South American Amazon basin, their vibrant iridescent blue and red stripes naturally evolved to help them stay visible to their conspecifics in dark waters. A fascinating trait of the neon tetra is that these bright, light-reflecting markings actually fade to gray or black at night when the fish is resting, only to reactivate and regain their brilliant color in the morning light.

In the home aquarium, Neon Tetras are considered relatively easy to care for and make excellent additions to a peaceful community tank. As shoaling fish, they are most active and comfortable when kept in groups of at least six, though schools of eight to twelve are highly recommended. For the optimal environment, they thrive in densely planted tanks that mimic their natural Amazonian habitat, requiring soft, slightly acidic water. With a balanced omnivorous diet of high-quality sinking micropellets, crushed flakes, and occasional treats like daphnia or tubifex, these dazzling fish typically live for two to three years in a well-maintained home aquarium, bringing a constant burst of color and movement to your setup.
