"Most nemerteans are carnivores, feeding on annelids, clams and crustaceans. A few species are scavengers, and a few species live commensally inside the mantle cavity of molluscs. Some species have devastated commercial fishing of clams and crabs. Nemerteans have few predators. Two species are sold as fish bait."mr_x is it reef safe,i have one that looks like that?
