These have been in the tank for a week or so. Low water flow, water parameters perfect (of course :wink: ). 40 gal tank 24" deep, lighting is 150w blue (20k?) hqi ushio de and 2 x55w actinic pcs.
The frag is just above the sandbed in the center. The open polyp is facing straight up and the others are aiming out and away.
WHEW.
What would you change?
