Sea Urchin Behavior What are they doing?

These two were put in the DT a few days ago. I noticed them "linked up" today on the glass. While watching them a shower of small differently colored balls came from one of them. Any ideas?

They were probably spawning. The link below might help.

The balls are poop. Those don't look like the same species of urchin... but I can't see much of the bodies.

I got them from Algae Barn and both are supposed to be Echinostrephus sp, But probably just poop like you say but the colorful type at that.
