Glowlight Tetra (Hemigrammus erythrozonus)
The Glowlight Tetra is a small, colorful tetra originally found in the Essequibo river drainage in Guyana but which is now commercially raised on a large scale in the US and overseas. In the wild, this species is found in a variety of habitat types, usually in large schools. In the aquarium, they are hardy and adaptable, making a great and vividly colored community fish. Like most small schooling tetras, Glowlight Tetras are best kept in groups of 10 or more, and will usually school with other similarly sized tetras.
