Clown fish questions

[Acipenser]

I had a pair of clowns that I got when they were tiny one was about 40% larger than the other, I am guessing the female. I just got a 3rd clown much larger than the other two at least twice as big as the female in my tank . how long before the old female switches back to male and what happens with the smallest male ? Is this a going to happen for sure or is there a chance of the bonded pair to stay bonded ?
