    Default Nass or Whelks?

    Hi all, I've got a 58 gal with 5 "Nassarius" snails. They stay in/on the sandbed except during feeding. They emerge, and zoom all over, including glass and rock, trying to get food. On two different feeding occasions, I watched a "Nass" take a perfectly healthy trochus right off the glass and eat it, the other time, a cerith. I've also got 2 ceriths rolled over, not yet dead, but not doing well, I am suspicious the "Nass" are to blame, although they haven't finished them off, which is weird.

    So are these whelks? I looked here - Whelk versus Nassarius | Melev's Reef

    Evidence for Nass:
    Fast
    Buries in DSB
    Scavenges - have seen them eat known dead/dying snails that they did not attack. (I acclimated some poorly once and had high mortality)

    Evidence for Whelk:
    While it doesn't visually perfectly match either mollusk in the link, it's closer to whelk
    Attacking other snails that, as far as I can tell, were healthy.
    Has operculum

    I am thinking of taking these back to the LFS who sold me them, they have been really good and should know better if these are whelks.

    Thoughts?

    My vote is for whelks. 1. They don't look like any nassarius I've seen. 2. The fact that you saw one eat a healthy trochus.
