Plus they're awesome fish!!! I really want to get a 4 lined. From what I understand, in a large aquarium, you can usually keep more than 1. However, they will compete with any Dragonettes for food...just a word of caution.
Are we talking flukes now, or AEFWs.
Ive been told that a melanarus wrasse will eat them, and a leopard wrasse will. I have them both and still have plenty of AEFWs to kill all of my corals.
Honestly, if one of my fish started taking alot of interest in my corals it would probably be removed from the tank.
Sid, Id think twice before adding either of those wrasses. They tend to be extremely aggressive. My four line killed two new additions and was working on the third when I stripped my 120 down to the sand to catch the little killer.
