Since no "experts" seem to be answering I'll step in....
As you were told before, I would go as small as possible. If you do get that 2" fish, that MIGHT be acceptable. Marroons will fight to the death before succeeding the female position to a similarly sized potential mate. If there is any doubt about who's dominant they will rip each other apart.
I personally would wait for a 1" fish to turn up.
EDIT: Sorry reefman13 we must have been typing at the same time.
