Note that Nassarius Obsoleta are not the same ones available from most LFS. Nassarius Obsoleta are from cooler waters (much like Margarita snails). I think they behave differently from the "regular" Nassarius snails as well (Nass. Obsoleta actually eat algae whereas the other Nass. Sp. snails are carrion feeders). Just and FYI.
