Sexing and fungus preventative?

If you want something easy, do guppies! Toss a couple in a tank and watch them multiply! I started out with a dozen or so guppies and now have hundreds. I have so many, I sell them on my aquarium forum. Pretty much all you have to do is have a clean, stable environment and they'll do the rest.
