Water motion is right, at least I think so, will post a video soon. got a water change scheduled tmrw, being my sg up ans bring phosphate down. As far as something picking at it...the only thing that would, would be the banded coral shrimp, but never saw it picking at it. I noticed that it's tentacles are starting to lose color, possible bleaching maybe? How do I go about taking it off the rock without damaging the other corals?. Last thing I want is for it to die and making a mess in the water? QT ready for it.
