Yeah, I agree with Toxis. If you are going to breed, breed to get some more hardiness in the Guppies.
What I'm doing now is getting very dull colored Guppies (Usually Males) and breeding them with SLIGHTLY more colorful females. These Guppies have some color..more plain though, like all yellow, or red with yellow. They are still very pretty though, and I have a few that have been with me for 2+ years... It's not the fancy shmancy, polka-dotted huge tailed Guppies...but I like the way they look. More natural.
So if you can, try to make the Guppy a better, hardier fish.
