IME it really matters which maroons you have, gold striped or white stripe. Like Peter I got rid of my white stripe pairs because they don't just damage each other, they flat out KILL each other. I had TWO survive to market size from a group of 60-70, they methodically killed off every other fish in the tank. Just when I thought I could call them a "pair" the big one turned on the smaller and killed it, so ONE fish made it to adulthood.
GSM's on the other hand are easier. Yes they fight and you will get some torn fins but they heal quickly and you can sell them. You might have more culls than you would with other species though. Packing them is a good trick, your 25 is waaaay too big for a couple dozen 2 month maroons.
A few months ago I learned that rasing tomato clowns with ocellaris mixed in really cuts down on the aggression. I have no clue why but maybe it's just confusing or distracting to them. I finally have gsm's again so I am trying it out, growing them out in mixed bag tanks with o's, tomatos and mollies. They are still young, time will tell if this works.
