What is this on my kryptonite trumpet frag?

Can anyone tell me what this is on my kryptonite trumpet frag? I've had it about 4-5 months and one head split but nothing much else. It looked and still does look great. Since I started feeding it regularly (thawed Hikari mysis) and getting all my numbers stable I noticed this. Is this growth or is it something bad?

They're vermetid snails - likely a result of your feedings. They are filter-feeding worms that tend to increase in number with higher nutrients.

Will they harm lps coral or anything else for that matter? How could I get rid of them? There's some on the base of my froggspawn too and it has been retracted a bit the last two days.
 
There's some debate...their mucus strands they use to catch food particles can annoy some corals, and corals that grow over their shells can be a bit deformed looking. But, as far as really truly harming corals...I don't think so.

Getting rid of them is a losing battle once they're established. You can clip them off of frags with some bone cutters or you can place a dab of superglue over each hole entrance. Or, you can fight them all by getting your nutrients down (skimming, reduced feedings, growing macroalgae, increased water changes with RO/DI saltwater, running GFO, etc.)
 
So since I've only seen these guys on the krypto trumpet frag and the frogspawn frag I took a bowl of tank water and removed the trumpet, placed it in the bowl of tank water and crunched off the "shells" with a needle nose pliers. Then repeated on the frogspawn. I think I got all of them off but my frogspawn was glued down so I had to use a little force to unglue it. It came off ok but i dropped it and a little tissue came off a couple of the tentacles. Now it's completely retracted. i hope it will be ok. Thanks for the info. Hope I haven't done more damage by trying to get them off of there.
 
Keep an eye on the snails.
Many times they will grow back.

I definitely will be keeping an eye out now that I know what those guys are. I"m new to reefing (1 year) and don't have many corals yet. I've noticed this for awhile but thought that the trumpet was "budding". I research every free moment I've got for 18 months and never heard a mention of these kind of snails. Thanks again to both of you! I didn't have a clue
 
Cool.
To be clear, what I meant was, simply breaking their tubes (more often than not) does not kill, the snail.

Ahh I see. OK I will look for any further building of tubes. If and when they come back I will do what you suggested. Thanks again
 
I've also been told you can superglue the opening shut. Never tried but makes sense, anyone else hear that or had success with an attempt?
