Looks great! You did nail it, from what I've read and heard, species like a. spathulata, humilis, gemmifera, samoensis, robusta, etc are commonly found in the reef crest zone. That humilis is looking nice and bright, how much par are you hitting both with?These are my two that I would consider reef crest Acropora. At least they are in the most “reef crest” like conditions in my system

That seems to be around the middle values I've seen many people put them at, and some of em can just downright glow. I've seen some that tenuis can only approach with special filtersThey are both in similar locations the Spathluata is probably getting just under 700 and the Humilis a little over. The Humilis is by far the brightest coral I've ever seen
