I would use a combination of Geisemann bulbs, they have the highest PAR and PUR of any T-5 fluorescent bulb. Using bulbs for tanning your fish WILL INCREASE ALGAE in your tank. Be prepared for that. A UV sterilizer on your tank will help. Choose a combination of AquaPink, AquaBlue+ and AquaFlora. This combination will give you the best chance of causing a skin coloring, light induced reaction.

This combination of lights will also allow you to SEE the color better when your fish finally does react to the food and lighting. Your fish will also be healthier as these frequencies will help it process calcium, magnesium & Vitamin D3 better.
As for the shipping price for the foods I gave a link to, you just need to email THEM. It's been a few months since my last order and I don't recall the shipping prices.
I use tropical almond leaves myself. Several peeps here grow them. Be sure to always say TROPICAL before ALMOND or some guy from California will go out to an almond grove and dump temperate almond leaves in his tank... Not the same species, or even genus!!!!Use blackwater extract or almond leaves. It may help, check out my thread at the media lounge.
