they only fight when they are in heat it is normal
They where probably fighting over territory. If they where both males then that is the cause. But, some hamsters just don't like to be with other hamsters. You could try to switch handfulls of bedding everyday so they get used to eachothers smell again. Then you could try to put them back together again. If they still fight then separate them and keep switching the bedding.
they are fighting over it . the one female does not want the other one to get it
You cannot stop two hamsters from fighting. It doesn't matter what two genders they are, or how young or old. They will keep having that urge to fight with each other. The only way to prevent them from fighting would be to put them both in separate cages, each cage a large enough cage so they could each have enough space that they are comfortable with. There's that way, or you could always sell one if you wish to take that route. I've dealt with hamsters before.
It depends what you did before it started hurting there's medicine you can buy
Dryness
They were fighting because i think Mariah started it first than Nicki ended up saying im gonna shoot you than they started fighting
they started fighting right after the battle of Saratoga
it made them very sad and depressed, so everyone started pulling out their hair and munching on bacon and then they all went out to parties together with their pet hamsters and created LICORICE.
