So I've had a frag for a while now. It appears healthy with lots of horizontal growth and really good PE. It used to be very green with the red polyps. As I moved it closer and closer to the spot I want it it has changed color. It's probably like 5 inches from the surface with another like 14 inches away from the 150w. The green has faded, as expected, but it seems to be getting more of a light brown. I can't really tell though. It almost seems like it's bleaching but I don't really think it is. Are there and zooxanthellae experts? I'm thinking maybe it's still transitioning to the red color.
