I have a Scott's, Exquisite, Laboutei's, C. Cyanopleura, and Red Margin wrasse in a 120gal just fine and I know that the Laboutei, Scotts and Exquisite are males. I think my C. Cyanopleura is a female solorensis. Just make sure that the males are different looking like you don't want a Lineatus and Red margin together and such. Most places don't carry females since they aren't as well colored as males, most of the time I see females they are females of the pricier wrasses(Rhomboids, Flame...) Brian at Twilight aquatics sells females but they are the more expensive wrasses and I have seen Petsolutions sell female Laboutei's wrasse.
