i have a 150 cube reef two tangs and clowns lookin for some peaceful non aggressive wrasse like too have atleast three . need help choosing and finding some
Yellow "coris" wrasse - actually in the Haliocheres genus and good for taking care of flatworms
Most of the fairy wrasses would be fine as well. I'm very partial to flashers, but I'm not sure what tangs you have. Melanarus (also in Haliocheres)are also very pretty fish IMO, but are tough on clean up crews. Leopards are very nice, but make sure one you pick out is eating as they are often poor shippers. Leopards and Haliocheres need a sandbed.
I have a 65g with a McCoskers, Linespot and Red Lined wrasse. They all get along fine.
Linespots are awesome and are a sight to behold when flashing; well all flashers are really. The Red Lined is out all day swimming through the rocks looking for food. Definitely check out the thread Evolved linked, I'd say it's the gold standard when it comes to wrasse info.
I am partial to some of the species of Halichoeres wrasses, such as H. iridis, H. chrysus, H. leucurus, H. richmondi and H. timorensis, though there are plenty of other reef safe and reef safe-ish wrasses.
