Guppies...they're the only one I've ever bred. Its super easy. Just make sure you have at least 3 females for every male because the males will harass the females. Other than that just sit back and wait and it will happen.
Guppies or Mollies. Although, if you are going for the more popular species I would say guppies. As for the fun raiser idea. I am not quite sure. How exactly would that work out? I would hate to see people taking home fish they don't really want just to help out a cause. You will end up with a lot of implusive buyers who know knowing about tanks.
oh yea... your going to spend more time and money on these fish then you ever hope to make. go sell candy or something. so many better ways for fund raisers.
it takes alot of work to keep the fry in 100% perfect condition. if you give someone a fish that dies in a week they probably arent going to want to come back (unless you offer a guarantee). livebearers need at least 3 months before they should be sold, convicts even more.

I said a fund raiser IDEA. That didnt necessarily mean that was my sole purpose for breeding. mostly for science. going for a marine biology major. just something i wanted to do. money isnt much of a factor. just difficulty.
