One could easily devote a lifetime to keeping and studying Wrasses and not even scratch the surface. Over 500 species, ranging in size from 1 inch to 6+ feet, have been identified. A great many adjust well to aquarium life, where they delight us with their gorgeous colors and ceaseless activity. Many, including the celebrated Cleaner Wrasses, can be kept in community tanks, but please read our species descriptions carefully before making your choice, as their needs vary somewhat.
