Common name: Money Cowrie

Monetaria is a genus of small to medium-sized sea snails, commonly known as money cowries. These gastropods are known for their shiny and smooth shells, which have historically been used as currency in various cultures. In the reef aquarium, they are appreciated for their scavenging abilities, helping to keep the substrate clean by feeding on detritus and algae. They are generally peaceful and can coexist with a wide range of tank mates. Their presence adds a touch of natural history and can stimulate conversations about the fascinating use of shells as money.
