Fine looking corals. Good job overall technically. And probably not the easiest venue for shooting. Thanks for sharing.
You asked for opinions, so here a few. You obviously know what you're doing, so don't let me derail you. The last shot looks a touch over flashed. As photos, I prefer the ones like the trachys (lobos?) which aren't center composed, though at a show like that I'd have a hard time not taking center composed whole subject pics. On those, I'd probably crop aggressively to feature the very interesting colors and textures and to lose the whole piece frame of reference. Could result in some neat pseudo macro type images. The sparkly favia shot is closest to that though I'd go tighter still.
