Breeding...condition the female and male first(takes about 2-3 week). Let them see each other about 10-15 hours a day. Soon the female will be loaded with eggs, when it looks like her stomach is about to break open or if you see eggs falling one by one...she's ready. Make sure you prepare green water(infusoria) as I recommend them if you want the best survival rate out of your betta frys. Egg yolk is too messy and betta first bits will only bring about 1/4-1/2 survival rate as most of them will be looking for mainly something a live and moving to eat. Sponge filter, they do okay but I don't use them. I let the plant take care of that for me. Using a tub is great, but I prefer using an all natural clay pot as they contains minerals that will help the frys grow better and healthier. Well let's say you can put the fry in natural clay pot after 3 weeks. You can start feeding them baby brine after 2 week...but at start i recommened infusoria, and trust me...feed them just before their yolk sack dissappear or else you won't be in time to feed them. Once they starve, they will die like flies. Most of the big breeder in thailand keep them in green water under the sun which commonly help produce infusoria so they won't have to worry about any feeding until 2 week. But overall, telling the truth...trying to breed in the USA comparing to thailand, its not going to be the same. Even though if you use everything the breeder in thailand use. The problem is...water quality. But that doesn't mean you can't breed good quality...just not much compared to thailand.
