I just went and took out 1/2 cup of CC off the top, just to kinda get rid of the greenish pieces. I didn't finish...I had only started... But in only 2 scoops (with a plastic spoon) I got TWO brittle stars!!! They were VERY tiny, and they made themseves into a ball and fell through the holes in the bottum of the spoon. But if I had two in that small amount of gravel, goodness, I hate to see what's in the rest. Any suggestions as to how I can save these critters if I ...when I do do my water change?? Yeah, I said do do.
