You can see some of the skeleton from very old die off in the back. I would guess pectinia but not spiky enough. Like a cross of a chalice and a pectinia. Lol. It sat at the LFS for 2 months and no one ever knew what it was. Today they offered to me cheap. Looks pretty sweet and unique. [attachment=0]ImageUploadedByTapatalk1342904799.512945.jpg[/attachment]
