Hi everyone, I've had my tank up and running for about a month and a half now. I was looking in my sump last night and found this with some pods around it, and it has me stumped to what it is. I'm sorry for the poor picture I went to go take a better one and it was gone! Hopefully not a bad hitchhiker.

Looks like Vermetid snail. It's harmless but the web like stuff it releases will irritate coral so get rid of it if possible. You can also crush and glue the hole shut if attatched to rocks

That's what I was thinking initially but everything I've read said they couldn't move. I took this picture and the next morning when I went to get a better one it was gone with nothing left where it was. I've Been keeping an eye out for it but have yet to see it again.
