Guppies are the one of the easiest pet fish to breed in captivity. They do it all themselves, the only thing you may have to do is take the babies out and put them in a different container because the parents may eat them. I found that none of my guppies seem to eat the babies.
Guppies will eat neons tetra babies but are not large enough to eat fully grown neons.
