Very nice photos!
Can I offer a quick suggestion? Depth of field sucks with macro photos of corals, but if you get the mouths in sharp focus, it can fool the eye and the rest of the depth of field problems will often be ignored. It's like eyes on animals with eyes. If they are in focus then you're golden. Unless, of course, there's some feature that you are trying to emphasize for some reason. In that case, you gotta do what you gotta do.
But, the colors are gorgeous and the photos are nice and sharp. Please post more!
