Black Neon Tetra

Hyphessobrycon herbertaxelrodi, have two horizontal lines across their body of white over black. Hailing from the Paraguay river basin in Southern Brazil, they only get to a maximum of 1.6 inches so they're great schooling fish for smaller aquariums. You can keep 6 of them in a 10 gallon. They prefer temperatures from 68-82° F and pH of 5.5-7.0.
