Yes you can but you should probably do after sexual maturity and get them neutered and make sure they like each other you should introduce them in a unknown area that they both don't know its normal that they ignore each other at first but you shouldn't pick the mate the rabbit should because they might live together for a long time!! so take you rabbit with you when you get another one. Also, bring a water sprayer just in case if they get into a fight you can break the fight!
If Japanese male fighting spiders keep fighting eventually there will be EXCTINT
Keep them away from each other.
Unfortunately there's nothing you can do except for separating them.
It could be 80+. There is nothing to be concerned about unless you are over 120.
keep them separated You can neuter them.
Nothing happens when you separate them. Nothing in particular anyway.
If that happens nothing will happen to any of the males.
They'll fight, and keep fighting until one of them dies....
Keep them separated.
depends if it goes to far with the fighting if it dosn't keep them together
No, after breeding occurs the male and female separate. The males have nothing to do with raising the young.
yes they can.
