they are either odly colored bulseye or green hairy, matalic green spots suronded by a purple background, their mouths are white. I dont think they are green yuma (wish they were lol), the dots are not prominent enough. They were be hind the filter out take, at the top of the tank (bad place, have moved them to the bottom, hopefully they are better). it cant be other corals as the only other critters in the tank are lots of pods, 1 skunk cleaner, 1 pep. shrimp, 3 button polyp colonys (very far away, at the bottom, on the other side of the tank), and 4 snails. I have heard of pods irratating coral, so think they may have something to do w/ it, but they are also constantly hunted by my shrimp.
will see how it fairs for the next few days. hopefully well.
