im guessing by 12..you mean 2.
no, take a female back and trade it in for a male. Rams to best in pairs. The third female will get chased and die eventually

Hi there,

Another thing to check when sexing M ramerizi (at least it works with the fish I have!!):

Along with the colouration and fins, the black patch on the side of the females will show some spangling/iridescence, this is not visible (the spangling) on the males black patch.
