Some very good advice given here already on breeding but just think of the time as well as the money. I spend 2 hours a day just water changing in my fish room and taking care of live foods etc for them. Read every single thing you can about it before you go ahead with it and yes, please invest in a good pair, it will pay in the end with good quality desireable fry
HI, if your male betta is a bit down in the dumps give him a mirror next to tank for 5 minutes or so. This wil make him flare as he will think another male is there. When you first get bettas they are very quiet it takes them a while to calm down.
