Wikipedia Abstract

Margariscus margarita, the Pearl Dace, is a species of cyprinid fish. It is demersal, freshwater fish, with a dark green back and silvery body. This species is omnivorous, consuming algae, as well as arthropods. M. margarita's range spans southern Canada and the northern United States. While not considered endangered at the federal level in the United States, several states either consider this species endangered or threatened; it faces threats of habitat destruction and invasive species.
