Aggression in male betta towards female betta

I recently tried to breed a pair of Betta fish but after putting the female in the tank with the male separated by a clear container, the male seemed really aggressive and murderous towards the female. The female seems ready as she is really plump with eggs, but I could not see the egg spot. Under her stomach. I tried releasing her when they were both sleeping which worked for like 5 minutes but when they woke up the male was violently chasing and pecking at her. I quickly seperate them right after into a different tank. The female seems really stressed out and is laying on its side breathing heavily. What should I do??

 

Have you watched videos on youtube about their courtship leading up to spawning? It is aggressive with the male chasing and nipping at the female all over the tank until she finds a good hiding spot (which is why you need lots of cover). The aggressive behavior can last a day, my pairs tend to spawn on the second day. Females can get torn up a bit but not too bad.

When the chasing calms down to just flaring, the female stops running away and clamps her fins while wiggling with her head down then you know they are close to spawning.

I hope you have all the live cultures for the fry when they are free swimming. They will refuse all dried/liquid foods if they do not move. This is why spawns often fail, the fry starve to death. I use paramecium and vinegar eels for the first couple weeks, then live BBS and micro worms. At about 1 month of age (or when they are growing pelvic fins) I start offering dry fry food (golden pearls, decapsulated brine shrimp eggs, krill meal etc).

 

Thank you demeter, I do have some daphnia and infusoria ready to go for the fries to eat. I am always ready to hatch out baby brine shrimps as well, but I would like to ask you would other foods like hikari first bites and egg yolk work as well? As these two are more accessible for me and is tiny enough for the babies in their first few days ( just unsure if they will eat it since it’s not moving)
Also, regarding the courtship for the betta pair, I have seen a lot of sources while researching on YouTube and Google, saying that the male should not be murderous and should try to impress the female by flaring and not trying to kill her, my male just straight up chases my female vigorously until the female lies on the side, stressed and heavily breathing. The female betta originally tries to approach him and follows him showing interest in breeding, but now the female is really stressed and keeps lying at the bottom of the tank. She only swims up to take a gulp of air, but roams at the bottom most of the time. Which makes me wonder if she is still healthy and capable of breathing. I still cannot find the egg spot on her though so was she really ready to breed?
Please help

 

How did you condition them beforehand?

Are you adding the female to the tank that the male always lives in?

 

I conditioned them by feeding them frozen shirmp and mosquito larvaes for a week. The breeding tank that I’m using is a ten gallon that they both live in it’s normally divided. I took out all the substrate and removed most of the plants so the tank looks completely different than the environment they used to live in. So it’s unlikely a teritorry issue
The female betta is a koi cellophane betta and the male is a blue and red crown tail. I am really excited to see what the offspring will look like so I really want them to spawn. How do you think the babies will turn out. Colour and tail shape wise.thank you
