Yup, and many people who claim to have success with them change their tunes after the 6 line hits puberty. I love the look of the fish, but until someone can find a way to genetically breed the aggression out of them, I won't touch one. Kind of like adding a dottyback to your tank. If money were no object I would get a 30 gallon tank and stick one in there by itself. With the other spectacular wrasses that are out there (ie Melanurus, Red Lined, Christmas) it is really hard to justify a 6 line.
