Brittle Star Behavior

[chiefifd]

Has anyone observed Brittle Star's seemingly standing upright on coral and releasing some type of cloudy substance from their I assume mouth.
I know I have a number of Brittle Star's in my tank, but never witnessed this behavior. Nor the number of Brittle Star's that came out of hiding after a water change. Usually only see the legs dandling form crevices or inside of the pump housings when cleaning.

That looks like a spawning event to me. Very cool!

I've never witness so many Brittle Star's come out and literary stand up. There must have been a dozen of them at one time. Wish I could have gotten better photo's, it didn't last long but, yes it was very cool!
There must have been 25 at least out, just checked, it's been about 3 hours since they came out. Not seeing one Brittle Star now! LOL
Thanks for replying :)
Oh my tank is a 90 gallon one
