Added some zoas to my tank about a month ago. Dipped them with Revive before adding to tank. Had them on a frag rack for a week or so and then mounted to a rock very close to where they were on the rack. They were opening really nicely until a few days ago. Now some open and others are not, and there appears to be some small black flecks on them. I have no other zoas, but several other SPS frags that are all doing well more or less. I do have a flame angel that's been picking at SPS, but haven't seen it pick at the zoas.
Any ideas what this might be and how to treat? I've moved them slightly to be in a bit less flow, but no other attempts to treat made.
