Female fighting fish attacking Male fighting fish?

[deadlymagicalunicorn]

I recently brought 4 Simease Fighting fish, 1 male and 3 females.
One of the females keeps on flaring up and attacking the male!

I'm not sure what i should do?

you cannot keep mixed-gender fighting fish together for this very reason. They're called fighting fish! Separate the male from the females or there will be deaths. You may have to split up the females as well.

How do they breed then if they can't be kept together?

You could keep females together at certain numbers and you could keep females and males together.

But these two statements all depend on the fish and its personality that's why it can be a shoot or miss which is what its like with all bettas and most fish, but not all "fighter" fish are nasty and i hate the reputation these fish have! But females can be kept together i think in 3s or 4s. I had my female and male together and they got on fine my female submited to him and they went on but my male is a wimp and gets bullied by everything so he has a nice 20G. Also a male and a female should only be together (if they do fight) when breeding time comes which is when i THINK the female shows stripes but some have striped bodies anyway like mine and when the male makes bubble nests but theres a whole lot more too it. Hope you house the male! If you have not already try get some caves and densly planted areas but it is strange your female doing that as females are more peacfull, it could be stressed due to ammonia etc though?

In the wild they have the ability to escape from each other - they only get together when conditions are right in order to breed. Google "Breeding bettas" and you will see that generally males and females are not kept together, tho many people keep female bettas (generally called sororities). The smallest effort at research would have informed you of this.

You'll have to get the male out of there, and monitor the females to see if they will form a pecking order.

Stripes on females (long term) are generally signs of stress.

Also, the size of the tank (I didn't see it listed in your profile) may be making them a bit more aggressive?
