does red/orange SPS need less light?

you should start them all lower in the tank and gradely move them up. Darker ones like to be around the middle of the tank unless you are in my tank I have a brown polyp with purple tip that likes it as high as it can get. and a green monti cap that likes it lower down. so in general try different locations the coral will let you know where it like s to be and then leave it there.
