why can't i keep a male paradise fish in a 5 gallon aquarium?

I was just curious becuase you can keep a betta in one and a betta is even lest hardy as a paradise fish.They behave mostly the same way and are both carnivorous.The paradise fish can be kept in small areas and oxygen depleted waters.So i just wanna know why can't you keep a pmale paradise fish in a 5 gallon aquarium.

You can. Paradise fish can live and even breed in a 5 gallon tank.
