I think this is the case with me, too. I have had brittle stars in the past, so I know what they look like. I definitely have about 3 of them living inside of the rock and sticking their arms out when the lights go out.
I think it is from when I bought the rock. There were about 10 brittle stars in the box with the rock. Living just fine. They were only about an inch in diameter, however. So, I believe they got down deep in the rock, and just live there sticking arms out from time to time.
Every once in a while, in the morning, there will be a brittle star arm curled up in the middle of the sand all by itself. Weird!
