All,
I've got one big and one little Green Toadstool in my 133 gallon reef tank. They've both been in the tank 6+ months and have experienced good growth. They are on opposite ends of the tank. I've had them close up for a few days before where they shed their skin. They usually pop right back looking better than ever. A few days ago, however, they both retracted their polyps and have yet to open back up. They don't appear to be shedding either. What concerns me is that they both closed the same day.
Can they sink their shedding? Is it possible that there is something effecting them, but not other corals? All other corals are look great other than a patch of zoas that are being bothered by some predatory snails.
The only recent change to my tank is that I added a Carbon / GFO reactor from BRS. I added the Carbon about 2 weeks ago and then some Phosguard to the GFO side about a week after that. It seemed to be a few days after the Phosguard that they closed. Could it be they like a dirtier tank or more phospates? I underdosed the Phosgaurd, as not to cause any big swings.
Pics below. Are they dead / dying or just doing their natural cycle? Thanks for your input.
