When we first got into fish breeding, my fiance and I bought some bettas from our local fish store(our first mistake). I knew quite a bit at this time about how to diagnose fish ailments, and they seemed healthy looking enough. These Betta fish had very beautiful colorations, but they were the veil tail genetic strain of betta fish, very outdated. We of course didn't know much about that sort of thing at the time, after all this was our first attempt at a spawn. We put the male and female beside each other in seperate clear tanks, so they could get used to one another. Then eventually we put them together in a sawed off gallon milk jug. We watched them perform coutrship rituals and got very excited. However this ended up in the female becoming stressed and laying on the bottom of the jug, so back they went into their separate jars. A couple of weeks later we put her into his jar and just hoped for the best. Several more weeks passed by, and they had seemingly establish territories, hers being in a floating plant, and his being sort of everywhere else. We figured they had just agreed to co-exist and life would go on, but one morning we woke up and 
mg: EGGS There was a huge bubble nest with eggs and the male was taking care of them, spitting them in the nest as they fell. After a while the female was removed according to procedure. And we continued to feed the male, he didn't have much interest in the food and the water became foul. We added conditioner but it wasn't enough to help remove the ammonia from the fish waste and the crap from the food in the water. We ended up losing the babies, and shortly after our male decided to commit suicide. 
We found him in our desk in the morning, all dried up. Lesson learned, don't remove a female fish before she is done laying eggs(we had no experience and couldnt tell), no more store bought, usually already in poor health fish, and make sure you have the proper equipment before attempting a spawn. A syphon tool would have been nice. Oh, and keep better lids on betta jars they JUMP very well.
Well, lesson learned, life goes on,
