you heard wrong about bettas being easy to breed. They not only are difficult to breed on general, but be prepared to have a great deal of room involved because you will need at least a 55 gallon tank to use as an intermediate tank for your fry until they start to show sex characteristics. Then you are going to need to have room to seperate all the little males from each other in jars and still keep the big tank for the growing females. And you also have to take into consideration that while the males are not in the big tank, each of those jars are going to need the daily water changes and the care that the big tank does. NO, bettas take a lot to breed. There is also the very real chance that one or both of your breeding pair may end up damaged due to the after-the-mating arguments if you don't get them seperated fast enough. I have even heard of more than one female killed by the male. You will also need another completely seperate tank of 5 gallons or so for the female to go to after spawning to recover and to prevent any chance of her getting infection. That means not back to the community tank. That is a lot of tanks and jars and work.
Hope this has been helpful. I like to see bettas find good homes, but don't buy one just because they are "easy to breed". You will be very disappointed and the fish will be unhappy.

A great read though....I found it very interesting and realized that bettas were difficult to breed, but until you really sit down and read about the work that would be involved you really don't see the big picture.
