You would probably get a better response on the for sale threads. But for Rics propogation is the best way to get them to multiply (especially the Yumas) I read an article on a beautiful red yuma that a guy had for a while and it just sat there so he got the nerve to cut it and then he had two. So he kept on cutting. From what I hear the Yumas are hard to get too but I don't know. I have yellow, blue, and green rics but they are too new to my tank for any fragging just yet.
