Recently picked up a frag from a local guy, and as I was leaving he warned me that he has vermetid snails. Checked the frag plug and sure enough it's loaded. So my question is, is there a way to rid the plugs of the snails? I hit the plugs with a brush to knock off all the snails I could and the frags are in the qt tank until I can make sure there are no more snails to infest to display tank. I have heard of a peroxide dip for other parasites and what not but I'm not sure if will kill of the snails?
