The Gold Ring Cowrie is a very peaceful species of snail and they are very beneficial to marine aquariums as they feed on detritus and will reduce the levels of algae in the aquarium. They have a white shell with two yellow-gold lines along the upper side which connect at the ends which create a near ring shape which is how it gets its common name. They make an excellent clean up crew by actively grazing on algae and detritus. They are Reef safe and a peaceful species but care needs to be taken when choosing their tank mates as more aggressive species could harm them so it is best to add these snails into a mature tank with established live rock
