Recently added a few new corals to my tank. There’s 2 I’m concerned about. I added them to the tank on Tuesday. My other corals before these opened up within the day they were added and have been fine ever since. I did a 50% water change on Sunday and my parameters seem to be in check. Is this a flow issue or possible lighting issue? Combo of both? Ones a clove polyp and the other a zoa.
