Can somebody ID these snails?

Hey guys, everytime i feed my fish, these snails come rushing out. You dont even notice they are there unless you look carefully and i never really see them until i feed my fish and then about 20 appear.....should i be worried?

I don't see any in that picture but I can tell you from what you describe are nassarius snails. They are one of my favorites, live in the sand and when they smell food it's like the zombies are attacking LMAO.
