Vermetid snails , the way I control or wipe mine out was with the help of melanurus and leopard wrasse.
I had a 120g about 150lbs live rock infested with vermited snails. To the point of I can't pick up a piece of rock without them poking my hands. It was even on my sps and every other coral and clams.
Well one day I was crushing those snails up with a stick and both of the wrasse was following me everywhere I was smashing them as they were eating them as I go. I would do this everyday training them that there is food under the shell. What do you know, they were at it a few days later without my help.
These two wrasses were very friendly and doesn't hide like the other fish when I put my hand in the tank. Month or two, later the snails were gone. Keep in mind that my tank was literally infested, even on my powerhead.
