Black Neon Tetra is a popular freshwater schooling fish loved for its elegant contrast, active swimming behaviour, and community-friendly nature. Its dark body is highlighted by a pale shimmering stripe and a subtle black band, making it stand out beautifully in planted aquariums with driftwood, rocks, or dark substrate. This species is well suited for beginners as well as experienced hobbyists because it is hardy, adaptable, and generally easy to maintain in stable tank conditions.
These tetras are at their best when kept in a proper school, where they display tighter swimming patterns, better colour, and more natural confidence. Black Neon Tetras work especially well in peaceful community tanks with other small non-aggressive fish. Their manageable adult size and calm temperament make them a great option for nano-to-medium freshwater setups.

Care Requirements
- Tank Size: A minimum of 45 litres is suitable for a small school, while larger tanks provide better swimming space and more stable water quality.
- Water Parameters: Ideal temperature is 22 to 28°C with pH around 6.0 to 7.5. Soft to moderately hard water is generally preferred.

- Care Tips: Keep them in a school, maintain regular water changes, and provide plants or shaded areas to help them feel secure and show better colour.
- Aquascape Preference: They look especially attractive in planted tanks with dark backgrounds, open swimming space, and gentle filtration flow.
For best results, acclimate Black Neon Tetras slowly after arrival and add them only to a cycled aquarium. A healthy school creates constant movement in the midwater zone and adds a refined, natural look to community tanks.
