Looks good Karin. From what I see of the pic, it looks healthy and should love all the food floating in the tank. I have noticed in my tank that corals will change color under the t-5 lighting if I move them around. My Red Planet is a good example - up high and it turns bright red w/ very little green - I put an accidental frag that I made of it about 6" lower and the frag is the exact opposite
