The best lights are the red ones, since I've read here many times that fish cannot see the red spectrum as well, so to them it's like being in darkness. However I wouldn't use one on an 's hardly natural for there to be that much UVA at night, and as you say fish don't have eyelids so it may keep them awake (especially if if whatever species it is can see well in that spectrum) just as much as a strong blue light would.īlue lights look great (and eventually I think I'll get one), and are fine if turned down very low - but the fish can still see it and while it seems natural to us, how often do you think shallow ponds/river get that much moonlight shining on them? The weak output of black lights should not cause DNA damage or cellular mutations the way sunlight can."Ĭlick to expand.But after reading the above, how can you say that? If the light from the tubes isn't going to be as bad as what fish would get from the sun anyway and some amount of the UVA is bound to be reflected by the water and even more wont penetrate very deep, I doubt it's going to do any major harm. The strength of a black light in comparison to sunlight is minuscule, so it is doubtful that UVA light poses any significant health risks. UVA light can cause DNA damage, but not directly like UVB and UVC, it does so indirectly by producing reactive chemical intermediates, such as hydroxyl and oxygen radicals, which in turn can damage DNA. UVA can also destroy vitamin A in the skin.
BLACK LIGHT FISH TANK PLANTS SKIN
UVA is capable of causing damage to collagen fibers, so it does have the potential to accelerate skin aging and cause wrinkles. UVA light is much lower in energy and does not cause sunburn. It is the higher energy (shortwave) light in the UVB and UVC range that is responsible for the DNA damage that leads to skin cancer. UVA is considered the safest of the three spectrums of UV light. "While "black lights" do produce light in the UV range, their spectrum is confined to the longwave UVA region. To quote a couple of wikipedia paragraphs.
