Soooo. I bought a fairly juvenile mystery wrasse a couple wks ago whose been continuously tormented by my four line wrasse. The similar appearance of the wrasses is one thing that I had overlooked when purchasing my animated newcomer. I also have an exquisite wrasse who seems to pay no attention to his new acquantence. I'm hoping that my four line wrasse's territorial behavior is only temporary and that the mystery wrasse will condition this unwelcoming behavior enough to survive. Any suggestions?
