wow that was a bad fight the chalice has some pretty bad scars also.. I'd leave them be for a bit as if there is any tissue it can regenerate quite fast as it does not have to regrow the skeleton. I have a Favia that is regrowing and doing well I bought it and it only had 4 heads and now it is up to about 7 or 8 in only 1 month. The skeleton rock is quite large maybe 5 inch by 7 inch. or larger I never measured I would say I am guessing on the small side. you may want to dip in some Lugol's solution tomorrow it may help in the healing process, I would have done the dip right away.
