Brittle star spawning event

I did a water change on my little 6gal fluval edge the other day and about 15 minutes later all the micro brittles started standing up and dancing, then spawning.
Here is a video link:

Mine do that too when I do a water change. I wonder what it is about the water change that triggers this.
