Trust me, I've thought about breeding them myself too. i studied the genetics behind it, the legal ramifications, etc., but I just never got around to actually trying it yet. I've always thought that it would be cool to have like a 20 gal tank with black gravel, the light that makes them glow, and a big school of them in there, but it would just cost too much if I were to buy enough of them to fill the whole tank. That would be too much money wasted on danios that I just want for the fun of it, as like a gag tank... They can go for as much as $17 a piece here in NH...
