Over the past 10 days, one of my new Zoas (put in tank on 12/6) has started to invert it shape. It had the classic cup shape once it settled it. It slowing been inverting it's shape now though.
Any thoughts what could be causing this? Other Zoa's in the tank seem happy enough...although it should be noted I believe they are reaching for some light. The Gobstopper (Red one in 2nd pic) is also opened up more broadly, and less cup shaped then before. I attached a picture of my lighting schedule, if anyone has thoughts to the intensity I'm happy to listen. It's a modified Saxby schedule. I decreased the overall intensity by 40% of original, then halved the white light intensity again for my desired look. Tank is a IM 14G Peninsula.
Parameters:
Temp: 78
Salinity: 1.025
NO3: 12
ALK: 9.6
Ca: 415
Mg: 1215
PO4: .03
Thanks in advance for any thoughts.
