A peaceful schooling fish, it does best with a single male and several females. General body color is yellow/gold with black leading edges to the fins. The male will develop red color on the anal fin during courtship. The split dorsal fin and extended anal fin give the fish its distinctive shape and a “twitching” motion when it moves. Only growing to less than 2 inches in length, the Signifer Rainbow makes a great addition to a Community style aquarium. They prefer a generous space for schooling.
