Not sure what to call this exactly, but the guy at the LFS said it was a leather and what I have seen from pictures it looks like a Colt Coral. Either way it is has looked different in the past couple of days.
It normally goes from big to small (what you see in the picture), but in the last few days it hasn't come out of its "funk". I have noticed a little bit of brown film around the bottom and some brown "fingers" on the branches. I have read a few posts that it might just be "molting" (not sure what the correct term is). I have it about half way up in a medium to high water flow. I recently did a 15% water change (could it be stressed from that?) and all of the other coral and inverts look great!
