The thing is they are both male's. And like my male A. Saggitae is at the size that they start getting thier big boy pants and attitude. I recently had to remove all the fish from his tank due to aggression.
Best bet is to seperate them to let the weak one heal up. Then rehome the little fellow. My male has already killed off a competitor male and his first wife. They were all in a 6ft 125gal tank and still had the same aggression issues .
My male A. Saggitae Casper at 6in.
