Neon Tetra natural habitat

The Neon Tetra (Paracheirodon innesi) is a small, colorful fish native to the clear, slow-moving waters of the Amazon River Basin in South America. Its natural habitat includes the streams and tributaries of countries like Brazil, Colombia, and Peru, where the environment is shaded by thick jungle canopies. These waters are typically warm, soft, and slightly acidic, with temperatures ranging between 20 to 26 degrees Celsius (68 to 79 degrees Fahrenheit). The rivers are often tannin-stained, giving the water a brownish hue, which helps Neon Tetras’ vibrant blue and red stripes stand out, serving as a means of communication and predator deterrence.

In the wild, Neon Tetras are found in large schools, navigating through dense vegetation and leaf litter that provide shelter and feeding grounds. They primarily feed on small invertebrates, plant matter, and organic debris. If you’re considering keeping Neon Tetras in an aquarium, it’s essential to replicate their natural environment. Maintaining the right water conditions, including a slightly acidic pH (around 6.0 to 7.0), dim lighting, and ample hiding spots, will help these fish thrive. Additionally, keeping them in groups of at least six will allow them to exhibit their natural schooling behavior and reduce stress.
