I have a pygmy chameleon, and so have been researching about them, and their needs. (oh so many needs! lol!) I came apon a REALLY good page on lighting and thought- Well, wouldnt fish get some UVA/UVB lighting in a natural habitat? Im wondering if it would help with lifespan, colors, health, etc. just a thought...

Everyone should read the one on flourascent tubes though, its amazing how fast the deterierate! In fact, i think i may change my one on my 16 soon! And the one, how much light so reptiles need, if the one that got me thinking about the goldies. They were saying that even nocternal lizads will get some light, that enters their hideout or what not. how much light are our fish getting? how much would be bad? how much green water!!! XD
