Mini brittle star!!!!
They are a VERY good clean up crew and they can spread pretty fast.

+1. They are great for the tank. Feed a little rotifers in their area an dawn/dusk and watch them go nuts!

"Look at me, I'm cute, feed me bish"

Could also be a banded serpent star I have one and he gets around quite a bit! Feed him from time to time

I feed mine frozen/thawed brine shrimp and she loves it. Mine is a harlequin serpent star

I have so many that when I feed the tank my rocks look hairy. They do spread like crazy but as mentioned above, they are great CUCs.
