I have an acro (fresh from Aussie waters) that I just got and it immediately turned brown. I understand that it’s the color of the zooxanthellae within the coral itself, covering up the natural color of the coral itself. Perhaps it’s due to high PO4 and NO3. Is this something to be concerned about or is it bad for the coral? I don’t care much about the color but more so the health of the coral itself.
The polyps come out slightly during the day. Don’t see them coming out after lights off.
