I got some zoanthids like 2 months ago, and I haven't seen them open in weeks. Granted, I have been having problems with dino's lately but all the other corals including 2 different zoanthid type button polyps I have opened except for these ones. They haven't died or seemed to dissappear so I wasn't sure what's up. However, I found one of these on the frag plug, at first I was thinking sun dial snail but it looks more like some type of miniture bivalve. Could this be the problem?
