Dunno if I'd go that far either, they can be very aggressive to other fish and invertsim about to throw a 6 line in and see if nature corrects itself...
@PatioIn my opinion the 4 line wrasse is prettier and in my limited experience behaves better than 6 line wrasse. (I’ve only ever had one of each though.)
I have a pink streak that a friend gave me when he shut down a couple years ago. It’s pretty cool looking and very friendly so far.
