Ive had this yuma frag for 2 weeks, got it locally so it wasnt shipped. I dipped it and ran acclim mode on my lights for about a week. It is on the sand bed with low flow and low light. It had been about halfway opened the last couple days, not full, but not shrivelled. Today I came home and it had let go of it's attachment. Why? I'm figuring either light or flow but I really don't think either are too high. I have a kessil ap700 mounted 18 inches above the waterline, and the coral is another 20 inches below the surface. I have them only get to 50% for 4 hours. I have two florida ricordea a couple inches from the yuma that appear fine and fully open. Any ideas? Thanks
