Rock nem excreting brown junk

[ahiggins]

morning all!
So yesterday I noticed that my rock nem was excreting some brown stuff, wasn't closed or anything so I wrote it off as pooping.
Then this morning I woke up and he was closed but the "poop" wasn't coming from his mouth. Since he was closed I saw it was coming from His skin, not his mouth or feelers. Pic will show it better.
I did see one of my red leg hermits next to him yesterday...could he have been munching on him?! Since there's no fish in this setup yet, the tank only gets fed when I feed the nems. About once a week.
Anyone have any idea? My other two Rock nems are totally fine and loving life.

It could be shedding some slime anemones produce a lot of slime this is resin from a carpet anemone I have all nems I've seen do this and he could still be popping or splitting if he's deflating like that I'd give him a day or 2 before you worry about him

this is just the regular slime anemones produce

That's exactly what it looks like!
Why do they do that?

Could be expelling zooxanthellae or waste. I've seen different causes including being burnt by lights, after eating, etc. I would keep a pretty close eye on it as it doesn't look super happy. You can suck it out with a turkey baster if you want.
