So I added the below coral (pictures attached) I was told they’re beginner friendly and fairly hardy. I added 2 coral last weekend that opened up quickly and are doing great. But these 3 that I added I have had in tank for about an hour and the 2 (coral on sand bed and the white coral) seemed to of closed up more than when I first added them. Should I just give them time? And how long should I keep tank lights off for them? The third coral seems to be opening up and doing okay.
