That's the problem. You are trying to pin me down while I am only talking about potential. I'm not saying that you should start using UV, only that their is nothing wrong with someone making the desicion to use UV. And I clearly stated that color was only one example of how it may be affecting the animals. It could also have indirect effects. Maybe it helps them cope with certain microbes or kills off certain microbes. Once again, only one example of a possibility.
