Hi i adopted two 8yo res(males) a couple of weeks ago everything was fine up until the last couple of days i noticed they are fighting a lot
(doing the mating dance ,one flaring its privates then fighting really aggressively)
do you think they have always done this or should i try and re-home one as soon as possible as i have no other tank to keep it in
don't really want to split them up as they have been together for 8 year but
they cant be happy if they are fighting
