A flasher wrasse may not do to well with other wrasse that may be aggressive towards it. However tank size may help if it is a larger tank. Six line has been one of the worst I ever owned.
Lol thanks Lenny I was thinking it would mine is nasty to begin with, I could only imagine another wrasse in there with it! Ill steer clear of it, and might consider a maxima instead!! Completely different end of the spectrum, but those were my top two choices or a new addition... I'm gonna do my homework and see how difficult maxima clams are
