questionable new addition

[milesj60]

Yesterday I bought my first zoanthid and today when I got back from school I noticed a slug like animal roaming around the tank near the zoo. It looks just like a slug you'd see outside just with a white coloration. Is he bad news or what?

if its any of these guys, then do a FW dip or lugols solution dip in a separate bucket...

I always dip every zoa frag I get before putting it in my tank. that is the safest thing to do. IMO.
