Black Neon Tetra (Hyphessobrycon herbertaxelrodi)
The Black Neon Tetra is a peaceful and elegant South American shoaling fish, loved for its bold black body stripe, bright silvery-white upper stripe and subtle red-yellow detail above the eye. Despite the name, it is not a true Neon Tetra from the genus Paracheirodon, but a hardy Hyphessobrycon species that makes an excellent choice for mature planted community aquariums. In the right setup, a group of Black Neon Tetras adds constant movement, contrast and a clean, classic look to the mid-to-upper levels of the aquarium.

I added a group of five Black Neon Tetras to my 20-gallon planted tank. They are very active and add a nice contrast to the greenery. The fish stay calm and don’t chase other species. After a month, they’ve established a natural school pattern and look stunning.
Thomas Gray –
The coloration is vibrant, especially the silver stripe and red-yellow detail. I keep them with neon tetras and corydoras. They don’t compete for space and blend well with the background plants.
Nicholas Metcalfe –
I was worried about compatibility with my existing fish, but the Black Neon Tetras are very gentle. They swim in the middle and upper levels, creating a dynamic flow. Easy to care for and maintain in a stable environment.
