Hmm, Sayurasem, I would hold off on breeding. You don't even have your males in proper housing yet, so honestly breeding is something you should wait for until you're completely ready, because breeding is a long process full of work, and it takes a toll on even healthy bettas at their best. Besides, think about it, you need a lot of things for the breeding to get done properly and to house potential fry, which you probably don't have.
Give yourself time to get your betta boys what they need first, and give yourself time to research. Here's a good place to start for researching :) http://www.bettysplendens.com/articl....imp?catid=855
