The black neon tetra (Hyphessobrycon herbertaxelrodi) is a peaceful and visually appealing freshwater fish that makes an excellent addition to community and planted aquariums. Its bold black body is beautifully contrasted by a clean cream-white stripe running horizontally along its sides, complemented by a subtle orange highlight above the eye. This refined coloration gives the black neon tetra a unique, understated elegance compared to more brightly colored tetras.
Black neon tetra fish are active swimmers that primarily inhabit the middle and upper levels of the aquarium, though they will occasionally explore lower areas while feeding. Their calm temperament makes them compatible with other peaceful fish of similar size. While adult dwarf shrimp are generally safe, very small shrimp and fry may be eaten. Larger, peaceful invertebrates are usually suitable tankmates.
As a schooling species, the black neon tetra should always be kept in groups of at least six individuals. In larger schools, they display more confident behavior and enhanced coloration. Being tank-raised, these fish are highly adaptable, though they naturally prefer soft, slightly acidic water enriched with tannins and leaf litter, similar to their native South American habitats.
Black neon tetras are not picky eaters and thrive on a varied diet. Feeding a mix of high-quality flakes, pellets, and frozen or freeze-dried foods such as bloodworms and tubifex helps maintain their health and coloration.
