Heterandria formosa Agassiz has been shown to be an omnivorous daytime feeder with a decided preference for zooptankton. Plant food may be substituted when readily available and preferred animal food is scarce. Heterandria formosa is selective in its food types and may resort to topfeeding when its preferred food is located on the surface film.
