There is a new light out called satellite freshwater led plus. It is fully customizable as far as color is concerned. So you can bring out the colors in your fish. I ordered two one for a 20 and one for a 55. According to the par data you should be ok with low-medium light plants. The light is on drs foster&smith. You may find it else where too. Type the light into the search here on this forum and there are a couple threads that will have more info.
I like full spectrum ( this includes red, blue, green) you have said the fish are the focal point of the tank. All white LEDs can wash out the color of your fish. I'm speaking from experience. My rams look at certain angles and when the are in shadows under large leafs. My rams under full sperctrum are incredible!
