Common name: Sand Sifting Sea Stars

Mellitidae, commonly known as Sand Sifting Sea Stars, are a family of sea stars characterized by their small size and ability to burrow into sandy substrates. They play a crucial role in the reef aquarium by consuming detritus and uneaten food, thus helping to maintain a clean sand bed. Their burrowing behavior also aerates the sand, which is beneficial for the microfauna and prevents the formation of dead zones. Mellitidae species are generally hardy and can adapt to a variety of tank conditions, making them a popular choice for reef keepers.
