I’ve had this meat coral for at least a month and placed it on in the middle of my tank on the rockwork but it never opened up fully. I have another acanthophyllia that is doing fine and all my other coral so i don’t think it’s a parameter problem. I just added it to the sand in the container today and it looks better than before. There is algae on the skeleton but it’s hard to remove it without touching the coral tissue. Any thoughts?
