My thoughts exactly.IME flame females all eventually turn male in smaller harums. I would do a rhomboid pair and a female flame. Or 2 female rhomboids and a female flame.
Any thoughts on Labout's Wrasse?
Can have a tendency to get aggressive with other Cirrhilabrus once mature.
Skip the flames and go with the rhomboids. That's my personal opinion, I tried flames twice and even with the male being the largest fish in the tank smaller wrasses bullied it. I figured the carpenters and whip fin at half the size wouldn't bother it. I was wrong they both pushed the flame male into a corner and I had to remove it. This was after using an acclimation box for 3 days with no indication from the other wrasses that they were even interested in the flame.
