I have had this snail for 2 years. I bought it because I was told it was a nasarius. But I did a transfer from my 100 to a 180 about 4 months ago and needed snails. So I bought a bunch of turbos from the reefgardner and when I let them out of the bag onto the sand my nasarius (?) came out of the sand and was crawling on them. To my surprise and shock it sucked the snails right out of the shells. I only had 3 snails survive this. I am getting rid of it because the reefgardner told me it was def not a nasarius but I would like to know what it is. Thanks for any help!
