Hey, Greg, beauties, as alwasy. That second one I have and am convinced it is not A. tenuis, as it doesn't have the roseatte form of radials. Only two come in question, A. selago, my choice, or possibly A. subulata, which should have less scale-like radials. This is a personal favourite with me. It produces quite a bit of branching making it different from the typical idea of A. selago
The first kid is probably A. valida, but could be A. secale.
There are quite a few corals I can't really place and think they may represent possible new species, depending on where you set the barriers. What is that question;'what is a species?'
