Should I be worried?

I just see his/her tentacles on the rocks for months and I finally see the entire body. Anything to watch out for?
We have mix reef with few fish, shrimps and snails and Fromia on standard 29g
Thanks.

Should be a micro ophiuroid brittle star, good to go, I have 200 ish. harmless

True, not the only one I see, about a dozen more but babies/little ones.

Harmless, and that is about as large as they get. Sometime when you do a water change or a sudden adjustment in pH they will all come out of their hiding spots and spawn.

Oh good about the size. I am afraid it will grow even bigger.
