The black diamond head neon tetra is native to the Paraguay basin of southern Brazil. In the wild, these fish prefer small tributaries, creeks, areas of flooded forest, and sandbanks. Their natural habitat is usually very acidic, and the water is stained brown from chemicals released by decaying organic material.
At an adult size of little more than 3cm, black neons are suitable for small aquariums. They are a schooling fish and should always be kept in groups of six or more. They also make a nice addition to a larger community aquarium, as they are peaceful and easy to care for.
Black Diamond Head Neon tetras do well in a community tank, as long as tankmates are not large or aggressive. They get along well with all sorts of other peaceful fish, such as rasboras, danios, dwarf gouramis, and other small tetras as well as corys and other small catfish.
