Ok, the polyps are coming back out, but the center of the colony, which had the oldest polyps and the largest (from the mature colony it was fragged off of) seem to have diminished in size, could it be this thing ejected it's polyps and grew new ones?

Also wondering, about 10 minutes ago I snuck a peak at the tank w/ lights off about half an hour, and the rhodactus mushroom I recently got looks STRANGE. The blue/purple and rust collored mottling is completely not visible, instead the whole thing looks like a silvery umbrella. The only change in the tank today was the running of the new 175 watt 10K metal halide for an hour...

Ok.. I just went in and looked again... and it is normal color again... did I just witness a feeding behavior? If so, that thing can open its mouth to an incredible degree.
