Looks like a harmless little sea slug to me. Your live rock is just that...full of living tiny critters. Just below your slug looks like a baby nerite snail too.... Bang Guy will know for sure.

I cannot tell, apologies. I'll need to see a clear picture of the other side of it.

It sort of resembles a Chiton but that's a weak ID without seeing the top.

Looks like a single leg of an asterina starfish to me. It even appears that it may have separated from the one directly above it...

Chiton is a sluggish looking critter w a slightly raised back rt?
