Noticed my Elegance coral had shrunken quite a bit lately. Took it out to do a dip and discovered an largish (about 1/2 in long, 1/4 in wide) orange patch on the side just below top edge of the skeleton. Hadn't seen it before because the coral expanded covered it. Poked at it and found that I could scrape it off, fairly easy.
I don't think it's coralline algae (because it's normally covered up). Is it fungus? Bacterial growth? Sponge?
Googling I don't see anything commonly reported on the coral forums. There are reports of an orange fungus infecting some coralline alge. Some reports of orange sponges. Unfortunately I scraped it off before I could take a pic.
