if there is a relationship problem with a current pair, you will know. the female will be actively tormenting the male, and many times kill it. so, unless you recognize the female actually attacking the male, i would just leave it as is. and when i say attack, the male will have damage.
i have a pair of clowns that bonded immediately after putting them in the tank. they were good for months, until one day, they werent. it was straight up aggression from the female. chasing the poor male in circles, up and down, and all around the tank. didnt matter how far away he was, she would go to her spot, and come back to find him across the tank, and do it some more. even when he hid under a rock, she would find him under a rock, and chase him away. i eventually seperated them, and took the male from my 65, and put him into my 20. i already have a pair of clowns in my 20, so i had to put in a seperator. i made one out of th egg crate material, but the male found his way to the other side. he was heavily damaged the next morning, but he was alive. i ended up making a better separator, and now the 20 is just split down the middle so i can have 3 clowns in it.
