Lol! Well, I guess I can add some value here since the pink and golds are probably from my colony that you got from Butts. If you are having them a bit browner than you like and you have enough nutrients in your system (good amount of fish), then blast them with light...they will color up nicely, pink skirt and gold disk. If you are still having trouble then you should take some nutrients out of your system or you just don't have enough light. In low nutrient systems and higher light, they get clearer...almost a transparency to their color...which is a look that you can see at Oceans Below. They look the best in my system eight inches from a 250W halide. Hope this helps.
