Only one falls into the "blue group" which is the group that loses the most coloration lacking a female. (I had to take out my pairs of Scotts because they were too aggressive) The ones that are in the "red group" tend to lose the least coloration, and the ones in between lose a little but not much coloration. Of course to retain the best coloration including nuptial colors, at least one female is desirable.
