harmful or Not? PICS

[Scythanith]

Should I be worried about this little guy? Looks like a brittle star but I haven't seen the body yet.

Any opinions?

Thanks for any help!

I agree with Marvin. I used have a bunch of those and all they did was irritate my corals and even my hermit crabs. Im not sure why but i dont have anymore.
