It's a brittle star . Totally harmless.

Looks like a brittle star, good cleaners and safe.

The mini brittle stars are good to have. The green brittle stars (much larger than that one) can eat fish and inverts.

Poor little fella is missing a couple of arms. Looks like he's growing at least one back.
