ease of breeding zebra danios?
im wondering how easy/difficult it would be to breed zebra danios. i have seen fry at a pet store i once worked at, and the fry grew up. so i know its possible.
my interest comes from looking at those 5$ glowfish (GM zebra danio). i think i heard somewhere that they are infertile, however i recall an article stating that someone illegally bred some glowfish in Europe. so it seems that it is certainly possible.
can those orange/red glowfish be bred? would the young look like the parents?
ill look around in google, but any information provided here is greatly welcome. thankyou!
