This guy is a major survivor! He's an original occupant from when I rescued the tank however this I'm not sure if him dislodging from the rock and forming those nodules as seen in the pics is a good thing or bad thing. He's not loose, still firmly attached so that comforts me. So I'm asking is this how they sprout new coral nodes or is this a more concerning problem
