You’re very welcome.
20 gal long would be ideal for breeding. I’d recommend 2 males and 2 females together.
They do not eat each other...however keep them well fed. As you can see, fry and adults eat together:

Types I know of: regular brown, long fin brown, albino, albino longfin, red, green, calico (cross between albino & brown). They’re all worth breeding. However, the albinos are much more in demand. Here’s a nice shot of a young male calico I bred showing the yellow and brown combination:
