Others have had luck -- and the size of your tank would help -- but this is something that I wouldn't suggest/attempt. It might work in the short term (( 2-3 years )), but that could all change when/if one pair starts to spawn. Maroons, in general, are pretty mean/aggressive, as far as clowns go.
And the kicker, what if it does go wrong -- do you have a back up plan to place the clowns after you catch them, which wouldn't be fun in that sized tank.
