I would move it higher. I have one on the sandbed under radions and it's red and green with pink new growth. Higher light more red, lower light more green.
What kind of lighting do you have?
I think red planet has great colors but it's a combo of alk and light intensity. Mine get 300-500 par with alk around 7-8 and all look like this. Usually though, higher light you get red/pink/white with very little green. Lower lightyou get more green and red generally.
I have three different ones in my tank in 3 different locations ( high , middle and low )
All of them are the same and seems the one lower too the bottom turns a much prettier shade of red pink and green
I think the water chemistry has more to do with it then the light factor.
I only run 3 250 w mh and VHOs for lighting on a 300 double deep tank . Been a while since I ran a par meter on the tank but it was only about 200 towards the bottom maybe lower
Sweet Red Planet they do love high par. Like many of the real nice corals to more par the better. But then they also need Full spectrum and don't like points of light spectrum.
