vermetid snails?

[SicZ06]

Got this at a swap 5/1 and was cleaning the tank yesterday. I am don't think they are good and scraped them off with a knife at the sink. What are the odds they will spread being in the tank for almost two months? Any advice would be appreciated, thank you! Sean

YES! Yikes it looks like you have a few on there, can you tank the zoa/paly off the plug? if not break the tubes and seal those bad boys up with drops of glue.

In two months it is definitely possible that they have spread to other places in your tank. Do you broadcast feed any particulate foods such as phyto, oyster feast, reef roids, etc? I find that tends to increase their spread. I would recommend inspecting your rock work to see if you see any others. You will definitely want to stay ahead of them as they spread quickly and are nearly impossible to completely eradicate.
