They are probably both male so you wont be able to breed them. Do you know the sexes?
Even if they are a pair, the fry wont survive in a community tank and without very tiny foods like baby brine shrimp or microworms and infusoria as well. You'd also need a seperate breeding tank realy - cause only the male should be left with the eggs and then he needs to be removed as well once the fry are free-swimming.
