Breeding to fund the hobby?

Yes, that's why I was thinking about them. I feel like the peacocks would attack them them though?

You could keep a single species of rainbowfish in the tank with them and have a clump of Java Moss in the tank. Each week you remove the Java Moss and put it in hatching/ rearing tank, and grow up the baby rainbows separately.

Would a single species of rainbowfish breed as above alongside guppies?
