From personal experience, I would be very hesitant to put another wrasse into a tank with an established six line. In most cases, they are highly intolerant of other wrasse species, and my sense is the six line would likely kill the newcomer. I've had sixlines kill flasher wrasses and pester fairy wrasses to near death. They are very territorial and aggressive.
