I have this unknown acrpora frag. I am pretty sure it’s supposed to be green but it looks like this instead. The tips are white. ALK 7.5 nitrates 5-10 phosphates 0.0 on Hannah checker, Temp 78, salinity 1.026, calcium 420. It’s about halfway up the a 90 gallon under an ATI Sunpower 8 bulb fixture about 10” over the water with 4 Blue+ 2 True Actinic 1 Coral + and 1 Purple +. I attached a picture of the mother colony as well as the frag. The branch to the right cracked when I was glueing it probably why it looks worse.
