Thanks Bill, the harsh reality of breeding bettas is that it isn't easy to get good fish, it is extremely easy to breed mediocre and "Pet" fish.
If any think its easy to spawn and breed great bettas and wow! I can make money!! Think again, Betta housing is expensive, it costs a lot to heat fishrooms buy good food or even cultures I can tell you I have about 5000 dollars into it and am just now getting my base stock.
Beanies to house the very best ones, Mason jars for the girls, I used to use a sorority but my fish are far to valuable to get one sick that can wipe out the rest.
There is a lot more involved then sticking 2 fish together and getting them to spawn, that's the easy part.
I have been trying to get the very best so that even if I give culls away they will be superior fish.
You must also build a reputation and I can tell you that is fragile and once you have a sterling rep, you must do everything in your power to pump out only the very best at all times, because you will not be remembered for all the beauties, its the Bad ONE you may sell to someone!!!
