Zoanthids. Good coral!
All I see are zoas. If there's something else in there that's moving around, can you get a better pic?
Not without some serious eradication:mrgreen:So best not to buy from that tank right? :(
None of mine looked like those either. But if they move to the glass overnight they aren't zoas. He didn't say how fast they move so I can only guess based on description.
Mine is 2'x2'x2' and reaching the bottom is still a bitch. I think my next tank will be large but shallow :P
