Rock excrement??? And acans? IDs??

[dlynch8802]

I was observing my acan today and found this white looking jelly growth on the side of the frag rock (not on the actual acan)

You can also see white strings coming out of the coral, which I know generally means the coral is stressed. Any ideas what it is and if I should remove it??

Also, while observing the acan, I noticed this pile of brown, what looks to be some sort of excrement, coming out of the rock.

I thought something might be hiding in that hole, but as I was looking at it, I watched the brown start coming out of a smaller hole below it. There is also a pile of dead Copepods right next to it

. I don't know if there is any correlation

Any help would be appreciated

That pile of junk just looks like detritus to me. As far as the other thing in not sure.
