I'm getting a skimmer from joanne on Friday. I did have a christmas favia that got stung by my orange crush acan (yes it is an orange crush, some of the new growth started turning green) and died. I didn't remove it because I was hoping part of it would survive, but it didn't. All the flesh turned to brown jelly and started falling off the skeleton, and I threw the remainder in the sump thinking that some pods or bristleworms would make a quick snack of the dead flesh. I guess that was a mistake.
