Found a few small Trochus snails and one Nerite dead recently....empty shells. Then yesterday I see this guy on the glass. I had nassarius snails in my previous set up and used some of that rock in my current set up. It's been up almost 2 years though and had not seen any nassarius (gave away all the ones I found when tearing down the old tank).
What do you guys think...whelk or nassarius?
