Black neon tetra

(Hyphessobrycon herbertaxelrodi)


Category: Fish



These natives of the Paraguay Basin of Brazil are recognizable by the two distinct, longitudinal, adjacent stripes (one white and one black) running from right behind their eye all the way to their tail. They are common aquarium fish that should be kept in groups of at least six or more. The feed only at the surface of the water so captive specimens should be kept with bottom feeders such as corydoras cats, who will gobble up their scraps.

Many do it, either naturally or due to environmental factors: fish, invertebrates, amphibians, some reptiles, even the occasional chicken!
