The Neon Tetra (Paracheirodon innesi) is one of the most popular and iconic freshwater fish in the aquarium hobby. Known for its striking colors and peaceful demeanor, this small tetra species hails from the blackwater streams of the Amazon Basin in South America. Since its discovery in the 1930s, the Neon Tetra has become a staple in community aquariums worldwide.

Neon Tetras are recognized for their vibrant and iridescent coloration. The upper part of their body displays a brilliant blue shade that extends from the nose to the adipose fin, while the lower part is characterized by a vibrant red stripe. These colors give the illusion of a glowing neon light, hence the name. Typically, Neon Tetras grow to an average length of about 1.5 inches (3.8 centimeters).

Creating a suitable environment is crucial for the well-being of Neon Tetras. They thrive in densely planted aquariums with subdued lighting, simulating their natural habitat in shaded Amazonian streams. A tank size of at least 10 gallons is recommended for a small group of these tetras. The addition of floating plants provides cover and replicates the shaded areas they seek in the wild.

Maintaining stable water conditions is essential for the health of Neon Tetras. They prefer slightly acidic to neutral water with a pH range of 6.0 to 7.0. The water temperature should be kept between 72 and 78 degrees Fahrenheit (22 to 26 degrees Celsius). Regular water changes help ensure optimal water quality.

Neon Tetras are omnivores with a preference for small-sized foods. In captivity, they readily accept high-quality flake foods, micro-pellets, and live or frozen foods such as brine shrimp and daphnia. A varied diet contributes to their overall health and color vibrancy.

Neon Tetras are known for their peaceful nature, making them excellent community tank inhabitants. They thrive when kept in schools of at least six individuals, and their schooling behavior adds to the visual appeal of the aquarium. When selecting tank mates, it's advisable to choose other peaceful species that won't nip at their fins.

Breeding Neon Tetras in captivity can be achieved with attention to specific conditions. Dim lighting, soft water, and ample floating plants for egg deposition are recommended. After spawning, the adults may consume their eggs, so providing a separate breeding tank with suitable conditions is often preferred for successful breeding.

Neon Tetra remains a timeless favorite among aquarium enthusiasts, admired for its vibrant colors and peaceful demeanor. With proper care and attention to their social needs, these tetras can thrive, adding a splash of brilliance to freshwater aquariums around the world.
