Maybe I can use my new fragging skills and cut get a few off of the rock in time for the swap. They reproduce like crazy. Here is a picture of what I purchsed about 8 months ago. 2 polyps on a small rock, one the size of a nickel the other the size of a pencil eraser.



That was when I thought they looked more like yumas. Now there are about 10 from the size quarter up to about 2+ inches in diameter and at least 10 more babies. The reproduce by leaving a fragment of their foot behind...not sure if that can help with the ID.
