Unless it's a male and a female, you cannot keep them in the same tank.
They will fight until one of them is dead.
=========================
This is not a good idea. I know this from experience. Unless the female is
ready to breed the male may constantly attack and harass her until she
dies - that is unless the tank is quite large and she can avoid him.
Bettas do very well in 1g tanks or jars.
