They have a colony on a rock about 7-8" across. I'd guess there are 15-20 polpys on it, maybe a few more. The story I got is they are unavailable from the store's distributors, but they have a client that bought a frag from the store many moons ago. That guy passes a frag to the store from time to time and is their sole source. She said they can't get any more in, so I don't know if that means the source dried up or if that's all they have for now.
