![]() ![]() the way UV light kills protozoa algae and other crap is by how much time they are exposed to this wave length and what part of the spectrum the light is. a UV sterilizer i think throws around 230nm. Either way this isn't a fish I consider supporting the development and sale of if that is the case. Others state that their fish are simply injected with dyes and many buyers have no problem with this while others think its the most cruel thing in the world. Some sellers claim their glofish (which are actually zebrafish) are genetically mutated to glo, and some will even go as far as to say that the mutation is natural and bred by selection. Which is a heated debate among many aquarists. I've seen blacklights used in some Fish stores but usually only in glofish tanks so that buyers would be more anxious to get a brightly glowing fish. I might note that I have actinics in my 5 gallon and they seem to supplement algae growth more than plant growth. Someone correct me if I'm wrong but the nifty ''accenting effects' a blacklight would create on fish (such as glofish) or neon decor is from the UV light it emits? I think actinics are also fine producers of UV light but are more for producing light utilized by corals in saltwater setups. Although I don't think they would be really harmful. ![]() I think blacklights would probably cause more harm then help.
