Common name: Peanut Worms
Scientific name: Sipunculidae
Sipunculidae, commonly known as Peanut Worms, are a family of unsegmented, marine worms that are often found in shallow waters and sometimes in reef aquariums. They are detritivores, feeding on organic matter and detritus, which makes them beneficial for the nutrient cycle in captive systems. Their burrowing behavior can help aerate the substrate, promoting a healthy tank environment. Peanut worms are generally harmless to other tank inhabitants and can be an interesting addition to a clean-up crew in a reef tank.
