Is this a Brittle Star?

[Tuffloud1]

I spotted a couple tiny looking tentacle looking things that come out during feeding.

It seems to be living between a frag of Monti and it's plug.

Is it a Brittle Star or should I be worried?

Mini brittle. Good for your tank. You probably have more than that.

next time you feed your tank get eye level with the sand bed and watch as they start moving the sand around it looks pretty cool.
