What is this? Looks somewhat like a freshwater ramshorn snail. About the size of a nickel. Maybe a little bigger. It is fused to my trumpet coral. There were two, and they appear to have killed the nearby heads.
Hmm…that’s what I thought was possible, but the others in my tank are like the size of a thick sesame seed. I didn’t realize they got that big. Perhaps the things I think are vermatid snails are not?
Yeah, that's a large Vermetid snail species; the big ones don't usually cause problems, but given where it was growing, I would not be surprised if it killed or at least irritated the heads.
Vermetids come in a surprisingly large range of sizes, so it's entirely possible that you have some small species in the tank as well.
