I like the 6line wrasses for the job they do, but don't like their disposition. I got a pink streaked wrasse about a year ago and love it. Very peaceful fish although it was very shy at first. It is coming out more now that I have more fish in the 120. When I had it in the 30 gallon it was only one of 3 fish in that tank so it swam out in the open a lot more.
