Black Neon Tetra
Hyphessobrycon herbertaxelrodi
Family: Characidae
📍 Paraguay Basin, South America
The black neon tetra has a distinctive two-tone horizontal stripe — iridescent white-green above a solid black band. Subtler than its neon cousin but equally elegant, it thrives in large schools in soft, acidic planted tanks and is very peaceful.
