I have a bunch of mini brittle/bristle (I have seen it both ways) stars in my live rock. I keep seeing their arms waving around. But my question is there a worm that has the same markings as a brittle/bristle star? I have these little clusters on my rock of what looks to me like really skinny brittle star arms. They have the same markings with the white/cream and black. But they are so thin - like needle point thin. And it looks like groups of 5 or so clumped together.
Any ideas?
Attached is the best photo i could get they are so small and hard to see.
