Green Iridescent Corydoras have a small spectrum of colors. As juveniles, they are lighter in color and appear light gray with an green and yellow iridescent tint on their sides. As adults they range from a dark grey to lighter grey and have hints of iridescent shades on their sides. Also known as Cory Cats, these small boat shaped bottom feeders make an excellent addition to community tanks. They will help keep the substrate clean, help with plant maintenance, and clean up leftover food. We have an assortment of Cory Cat breeds available.
