i have a fairly large brittle star for sale. He is large, maybe 9 or so inches in diameter. I will post a picture tomorrow, when I feed him so I can lure him out. He hides in the rocks during the day. I feed him small pieces of silversides about once a week. Unfortunately I have a slight aptasia problem and he loves peppermint shrimp. He also likes crabs as well. 20 dollars or trades for something.
