Having only recently been introduced into the freshwater aquarium hobby, the Glowlight Danio is still quite rare. These fish can only be found in the Irrawaddy River, located in the Myanmar region of Asia, and they are not commonly kept in pet stores in the western world. Glowlight Danios are one of the most colorful varieties of Danio, sporting bars, stripes and spots in bold colors like green, red and turquoise. These fish are best kept in large shoals of six or more to bring out the best of their coloration.
