Please ID white fuzzy stuff

this has just started to show up rather quickly and noticed it tonight when the lights came on and the corals were still asleep as I have been running a reverse lighting schedule due to tank temp problems. Thanks for the help the area is on the lower right corner of the coral.

Could be hitchhiker sponge. If so, no special care, helps to filter water.

You, probably, will get more responses about ID at the specialized forums - Invertebrates for this one and the crab. There are very knowledgeable specialists.
Just a thought.
