Why don't my beta fish get along?

I have a male and female beta fish and they dont like each other, they are in a tank together but its divided. they keep trying to attack each other. why?

Hi,

Betta fish are Siamese fighting fish. They've been used scientifically to study aggression, because if you put one in a tank in front of a mirror, it will try to attack itself.

So the obvious solution here is to get another tank and separate them. And don't put them in front of mirrors.

There's a reason why beta's are sold in single containers in the store, you're not spossed to put them with any other fish. Especially the males. Sometime's it's okay for the females though. Seperate them.

For some reason, betas don't get along.

You never ever put two betas together. The people at the pet store, or wherever you got them should have told you that.
