Oh wow I never knew that. How many could fit in a 10g?
I live in California; I support gene modification! (just not with "stuff" in my food supply!--well, at this point, I don't wanna be genetically modified either!)
How many you can fit in a tank depends on the size the adults will be, some say 1 inch of fish per gallon--all my tanks exceed that. However, I have excellent filtration, air, plants, water quality, UV, biological filters, etc.
I think those fish will light-up under a blacklight (the glofish), if not, some have been pulling my leg--knowing how bad that makes me want 'em!
If I don't run into someone, on the QT, selling them, or a friend to trade with me, I am going over to Nevada and snag a few! The LFS here got "busted" by the "holistic types" finding out he had them in the back room, and was selling them to favorite clients. I found out about that when I asked him about them (he showed me the newspaper clipping.) I am used to that, happens frequently here in the Land-of-the-Loonies (i.e., California.)
