Is my urchin pooping, or is this not normal?

Hi guys. I got a halloween urchin about a week ago and today he's doing something he's never done before. He moved to the highest flow in the tank and started letting out a huge cloud from the top. Is this just him pooping?

I put the best pic in had in case the link to the video didn't work.

No, not pooping, she is spawning. They do that when they are stressed or in a bad mood, sometimes when they are in a good mood or sometimes after a water change. So I don't really know but I know it's pretty common.
