I would get 1 male or 2 females, or 1m/2f. Two males will likely kill each other. It probably works well in your tank, Jeremy, because you have more than 2 gouramis.
Paige, if all you can find is males, then I'd get either 1 male or a group of them...like 4. That way the aggression will be distributed among them. Having only 2 males is asking for trouble IMO. Opaline gouramis (blue, 3-spot) are among the most aggressive gouramis. I have a male 3-spot in my 29g and he chases my glowlights, neons, and cories.
