! I may consider adding some to my tank since they're not all that much more expensive than regular dannies (and probably just as hyper!), if I can find 'em!

I think the homepage has a store locater link, or you email them.

And I imagine they don't fade like the "headlight taillight" or "highlighter" fish, too. Y'know, the clear ones with just a spot or two or a line of neon color (not actual neon tetras. Those buggers just do the flash-die on you a la Perfect Blue... >_<) and the color is gone in a week?
