Mystery won't tolerate those wrasses either. What's limiting isn't the mandarin, but the mystery or six line.thank you both. at this moment I'm now leaning away from a mandarin in favor of opening up some flexibility for different wrasses.
in addition to the ones you mentioned I'm reading more about melanurus, leopard, redhead solon, and the exquisite fairy. I'm still very taken by the mystery wrasse as well.
