So I picked up this leather at my LFS about 2 1/2 weeks ago. It looked like it might have been splitting when I got it? The week before Christmas, I went out of town for 7 days. During that time the power went out for at least 15 hours. I was unable to get back to do a water change until 3 days after that incident. My hammer coral, and 2 zoa colonies, where open and lively once the water change was done. My fish (2 clowns, 2 green chromis and 2 purple firefish) were/are amazing. This is what my leather looks likes now, roughly 28 hours after water change. So this picture was taken about 1 hour after the picture above (roughly 30 hours after water change). It went back to being all droopy after about 10 minutes. But notice the, what i think is a Waving Hand polyp. Would that be the culprit? I guess i'm looking for a possible cause? And should I try to save it or should I cut up the healthy parts and frag 'em? This is what it looks like now, about 70 hours after water change. This is a 37g tall that has been running for 2 years. My parameters are ideal.
