It all depends on the two males you have. Those of you saying that you can only keep one male per tank are completely wrong. Sometimes it won't work just because of the attitude of the fish, but if you get the right "pair" so to speak it most certainly will. I kept two males and 3 females together in a 75 gallon with zero problems. In fact they all shoaled around together, and one of the males and females spawned just about every week, and not one single problem. Try it if you want, but you really need to pay attention two both of them for a while and find out if it will work or not. If the tank is heavily planted and lines of sight can be broken easily, you shouldn't have too much of a problem in a space that size, but its still better to watch them and see how they interact with each other. If they start getting agressive with one another its time to remove one, its not worth losing a fish over. See as how I have done it, and know a few other people who have, I can't sit here and tell you that its not possible like a few other know it alls will. It is very possible, they also hardly ever fight to the death in tanks, the fish that do that are the ones that are bred for fighting and will if their owners let them. Most lfs bettas or show fish aren't bred for aggression. Try it, you have a 50-50 chance of it working, just don't let things get out of hand if it doesn't.
