I managed to catch some mini brittle stars releasing during a spawn. The star would rest then it would stand up on all legs and release into the water column then relax again. It did this for a good 5 minutes

Phil, I have lots. I could always meet you at the truck stop sometime like we did before and I could give you some. They usually get trapped in my powerheads etc, so easy to harvest.
