Hmm, interesting, someone else suggested that the coral looks like sun coral... though I also originally thought of a strawberry 'nem when I first noticed them. Actually, they look like a cross between the two, sort of... but they definitely have a low lying skeleton fused to the rock, so definitely a stony coral of some kind.
Suspecting the anemones to be Aiptasia the more I look at them. I need to get some kalk powder
