If you're new to bettas, I'd advise you to wait a little on breeding. :) I haven't done it, but it's expensive, time consuming, and takes a lotta betta knowledge. I'm sure you'll can it in no time, though.
Keep them happy by keeping them busy. Don't like give them a boring tank, each time you change the water, you could move some decorations around to mix it up for them. :) I do that for my boy, Wrigley, and he just patrols for a while and swims through the new decor! I also have a pet snail which he constantly is starting to harass, but that's besides the point.
These fish are seriously the bomb diggity, I hope you enjoy yours as much as I enjoy mine. :D
