hmm, I am sure larry can do more clarification, but it is my suspicion that after months in quarantine, both fish are already on their way, or have already become, female, if they are both female, then the fight simply won't end. (at least that is my understanding) on will eventually become dominant, but it will harry the other until it is removed, or dies of stress. I would hold out for a confirmation from larry though... I only have maroons and they are considerably more pugnacious than your fish. Heck, I moved both of mine tonight from the 30 to the 110, caught them both in the same net, acclimated in the same container, and they had been in the tank for no more than 10 minutes before the female got attitude and started beating on the male. Turned the lights out, I am hoping all will be fine in the morning.
"Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind." ~ Jack Handey
