The only species of wrasse I consistently have trouble with when adding new wrasses is the 6line. They really do need to be added last. Ive even had a 6 line harasse a new Mandarin.. I guess the colors were similiar?

Notoriously aggressive the 6line. With all the other wrasses out there, I would not even consider them these days.

my yellow wrasse went carpet surfing a few weeks ago, i knew it would happen eventually, he was always the most hyper fish in the tank especially at feeding time. on the other hand my blue sided fairy wrasse is 6 months and still going, but i definitely wouldn't trust him for 2 minutes with out the eggcrate lid on.
