I have had a bubble coral in my tank for a few months now and it was doing great and opening all the way with my maroon clown loving it. Now, it looks like two spots have turned black and it doesn't ever open like it used to. I do water changes every other week of about 45% of the tank. My other corals seem fine
Should I place closer to the light and not on the sand?
Does the base need to be in the live sand or can I place it on Live rock?
