Vermetid Snails killing my corals Help please!!

not to be a total buzzkill, but as someone how has fought this battle, nipping at the end of the tube doesn't mean he's eating or killing them. Snap some photos of the base of the snail, if it's not crushed open, they're not dead. Wrasses like that do eat off rocks in the wild, so pecking at the rock isn't unusual, actually crushing the base of the snail to get to the actual snail would be unusual.

Generally there are a few fish (the wrasse you got) that are "suspected" of eating them, very little in the way of proof and certain individual fish specific.
 
Well if you don't have any invertebrate's or anything in your tank that can be killed by copper medicine then you should try putting in a ick treatment that kills all invertebrate's. They may be immune to this or may not be. I am not sure. I have never had anything like that before.
 
well that was after a couple of minutes after the rock was dropped in the tank

I will keep an eye on the rock
 
I can't seem to get rid of them by starving them myself. I stopped all feeding except for pellets every other day. No luck.

I dose prodibio which is a form of bacteria/carbon dosing.

Not sure if this is "feeding" them. I am literally putting nothing else in my tank other than water changes and my calcium reactor with ARM media. I probably have about 300 of them. My nutrients are very low and have no visible algae in the tank right now. My water is clear as can be and rocks are deep purple. No clue what the hell these things are eating! :)

I am not sure if nets are killed nearby corals but there are definitely bothering them, I see many SPS frags with no PE covered in webs daily.
 
I have had them in all my tanks and they take over. They soon will be found inside your return pump tubes etc.

People say feed less, but I have not been able to get rid of them. I am starting a 200 gallon and I did not use my old real reef rock because they took over. Had to use new dry rock. Also, they grow on all your equipment. I have really good old real reef rock full of pods that I sadly have to get rid of.

I think these guys are underrated and worse than aiptasia. At least Aiptasia has a predator. I don't think these little shits do. The whole glueing is pointless because they reproduce at an alarming rate, at least from what I have observed.

There are different "varieties" of them it would seem. Some are quite large and others much smaller, with their tubes being only a mm or so wide. I have a smaller version, but they never "took over" I maybe had a couple hundred between my sump and underneath my live rock. A few here and there on top. Had a melanarus in the tank, and he didn't touch them. Gluing works if you only have a few and stay on top of new ones, but it is not an effective long term solution to get rid of them, there will always be some in places you cant get to.

I upgraded recently and tried to not introduce them into the new tank. I tried dipping everything in bayer and some things in iodine. Also manually removed all I could see. Neither dip seemed to kill them as I still had some come back. They are few enough that I manually remove them every time I seem them. They are only on my coral frag rocks/lps bases, so I can take them out, inspect, remove. I had some get on a rock, but I gave it an acid bath, and put it back in. So far, I seem to be winning the battle, but only a full system reboot with meticulous care afterwards will beat them.
 
That is where i am at...however trying to walk that path with a fully stocked tank is precarious

+1 to what Hippiesmell and Wzrdbear said back in 2010.

I have lots of these in all my tanks. And assuming different sizes indicate different species I've got different species together in the same system. And I've seen the same that Wzrdbear described back at the beginning of this thread. Looking at some of the responses ("vermitids growing through a monti"?!) and my understanding of how important feeding is to corals I gotta wonder if there's some other issue that's affecting the corals and not letting them compete and leaving food available for everything else. Unfortunately from what I've seen once this cycle gets going it's hard to correct using the traditional assumptions about limiting nutrients.
 
I'm in the same boat I have hundreds of these little pests, I did introduced a Toby puffer a week ago,
He did nip at little tubes but he hasn't touched the big ones
And also he got appetite for one of my tricolor acro hasn't touched other corals but just that one..
 
I have these growing in my tank in large numbers but they don't seem to have harmed any corals. I do have the grow on the bottom of mdntipora and in side the return box. So far they are just apart of the eco system. But I also have a pair of malunarus wrasse who seem to make it their job at ridding my system of any buggers. The female is a much better hunter than the male too.
 
Sorry becon776...
The Toby did Eat / killed a bunch of them.. BUT after a couple of weeks he developed. A GOOD appetite for some of the. SPS.... he left the Building.
 
Ok... so i have had a strict philosophy over the last 8 yrs of reefing NO CRABS! The other day randomly and for no real reason at all I added about 20 blue leg hermits, and 3 emerald crabs. These guys have been going nonstop. All the the web "trash" has been picked clean off the rocks. I almost thought i saw a emerald picking at one of the tubes.
So i am gonna go ahead and put 15 more in and 5 scarlet and 1 more emerald. Lets see. Maybe these guys got a foothold bc i didnt have and hermits in cuc for a decade.
