The fact that you're asking such a general question makes me think you're probably not ready to breed. You should have already researched a ton and maybe just have a few specific questions left over.
When will your fish arrive?
What was your original breeding setup?
No no, believe me I have read soo many different sites, and sources on ways to breed. But when I attempted I got so confused and I gave up! The first attempt I had a 15 gallon...with a sponge filter..fake plants, heater set to 78-80. a cup for the male to build his nest, I put the water about less than half way. Conditioned the water, used almond leaves. The first time the male made a bubble nest as big as the 15 gallon no joke, the whole surface was covered.
I obviously put the male in for 3-4 days, waited for him to make a bubble nest which he did. Then I put the female in firstly in a jar, then I tried dividing them with a divider as well. At first the female was interested, and she did have the dot shes apparently suppose to have. So I tried releasing her after a couple days. when I released her she was terrified...she hid in the corner for 3 days. So I removed her started over...The 2nd time she seemed better, she was going over to the bubble nest waiting underneath it, but the male kept chasing her away...and thats when she got scared again and hid in the corner, never coming out. I didnt know what to do after that !
My pair is probably going to come in august sometime, I have lots of time to research more and set the tank up.
Are you using IAL? that really help's a lot it help's the bubble nest stick together and not pop at all. Also your temp need's to be 82-86. I breed at 86, but thats just me. The IBC handbook say's 82-84.
What pair did you try to breed last time? Where did you get them from?
Where did you get the pair your going to breed now from?
On your breeding tank are you only filling it up half way?
Then next thing is feding them good food for 2 week's then put them in the spawn tank. Let him start building the nest as he see her, Keep feeding them good food atfer about a week. When she is flaring back that mean's she is ready. Make sure you have plenty of plant's. Also just because there's a little nip fins dont take her out. I put a pair together and on the 7th day i said if they havent spawned yet im taking them out. I went to check on them and they were doing it at last. Eggs every where. Some times a spawn can take a while just because they been together 2 days and nothings happen. Dont take them out.
First condition them on frozen or live foods for 2 weeks prior to spawning, don't let them see any other fish or each other.
Put them both in the spawning tank at the same time. Keep the female in a glass jar or breeder trap, etc. Once the male starts to make his bubblenest and the female is barred up and "dancing" you can release her. It can take a while but as long as the female doesn't exhibit stress (horizontal) strips you can leave her in there. A nip here and there and chasing is normal, unless one of them seriously injures the other don't worry too much.
I spawned at 82* within 24hours of putting the pair in the tank. I released the female within 3 hours of being in the tank. I did turn the light off at night which caused them to sleep instead of spawn overnight but some people choose to leave the light on, its a matter of choice and since it was my first spawn I was hoping to see it. The pair spawned mid morning the next day.
Your male sounds over aggressive. In your case, try using plenty of hiding places for the female to escape to; preferably plenty of live plants, concentrated at one half of the tank (away from the nest) then reduce the plants after they've spawned. Or you could use dull objects that can easily be removed once they've spawned. Personally, I would use live plants.
Some females easily get scared after a few bites. These females are more difficult to breed and often get beaten up pretty badly. But that's normal, it's their nature. You can try leaving her floating a little longer.
My question is; is the female really ready to spawn? Is she "dance" swimming like the male complete with spawning bars or is she flaring back in fighting mode? If she is ready, you need to give them more time. But if she isn't, you should remove her.
Btw, gorgeous betta. If I may make a suggestion, get a female that is a super delta or better yet, a perfect HM with anal fins equal in length with the tail fin (like the male). IME - Rounded tail females often produces RT instead of perfect HM. And longer anal fins will also be passed on to the offspring.
