Yeah mine don't look so great since i started pushing a little more flow at it tbh. You wouldn't think 30 par can make or break a coral but I do have a cpl shrooms with 15 par window and they suck. Ive seen gonis being ran on ab+ sps schedule thriving. Maybe they do need the heavier par to thrive idk.Some goniopora love sps systems and thrive well.
Very odd coral.
I'm going to lower flow on mine and see if it extends better for me. It was doing better before i made flow adjustment.
