6-line aggression question

[Myka]

Doug says "nems is evil", but what he really means is "6-lines is evil". I wouldn't be surprised if the 6-line did it. That's one fish that I don't understand why people buy it. There are lots of other wrasses that do all the great pest eating like 6-lines do, but are much more peaceful. If you can catch the 6-line, try a Melanurus instead?
