I have an open brain coral that was recedeing due high nitrates and my taking care of baby/dog/wife. I corrected the problem, should my brain start to grow back? I think it only lost 1/4" on 1/3 of the coral.
As long as your water quality is good it should recover, assuming it's not too far gone. I have had good success with corals coming back to life. You may want to try feeding it directly. If it is too stressed it won't feed, so don't force it, but see if it will take a piece of fish when you offer it. You may need to offer it a couple times, but it's worth a shot.
Only after you admit that the refs won the game for the steelers, and that the seahawks actually won the game on the field.
On a coral note, I have had LPS grow back from non existance. I usually am given dying or "dead" corals by the LFS because I have a habit of bringing them back to life. I have about a 75% rate with it. Tubastreas and LPS are the usual suspects. As long as your parameters are ok you should be able to recover them. I have one branch of caulerstea that is about a year old and is just now making a good enough recovery that I will consider taking it to a store for credit.
