Danios and Minnows are small, active schooling fish well suited of the community aquarium. Long finned varieties as well as different color forms of these fish have been developed through selective breeding, making Danios and Minnows very appealing to aquarists new and old alike. These hardy fish are most often used to cycle a new aquarium, as they are more tolerant of a wide range of water conditions. Danios and Minnows are also used in aquariums to help bring out the more reclusive species that tend to hide among the décor in the well-planted or highly decorated community aquarium. Found predominately in Malaysia, Sumatra, China, and India, most species are farm raised in both the Far East and the U.S. Danios and Minnows require plenty of swimming room and a tight fitting lid, as they are prone to leaping out of the aquarium when startled.
