Help ID these things near my Xenia

[fluked]

Have these things that sort of look like eggs on my Xenia rock, the coral is a bit retracted now (it retracts like this most afternoons, maybe that's a symptom?) Anyways, any ideas/suggestions would be appreciated. Thanks!

Looks like a Nudibranch of some sort. Is it moving or staying stationary?

Thanks! I've been lurking for a while, but deciding i should get some info on this so i joined. No movement at all that I've noticed.
