I have the same ones. I bought them from an LFS as a 4 polyp frag and now it's about 15 polyps. I just keep them separated on a rock and my clown seems to enjoy hosting them.Under blues, they *kinda* look like mohawk palys/zoas, but I can't give you an ID. I accepted them to be generic brown palys. As for the last pic, it does look like a stretching yuma (but no guarantees)!
