Hey everyone, I have had my male Earmuff wrasse since November of 2011 and I absolutely love him! He is a very peaceful fish and has never shown any aggression towards my other wrasse, which is a Mystery Wrasse (Pseudocheilinus ocellatus), or any of my other fish. Nor have any of my fish pushed him around. I don't know whether or not he would behave the same way with another Halichoeres. With that being said, he does show interest in snails and other small inverts such as hermits. However, he does leave my coral banded shrimp and tiger pistol shrimp alone. He readily accepts most forms of food and primarily lives on mysis shrimp. He has been a very hardy (never been ill, malnourished, or shy) and active addition to my tank and would definitely recommend one.
Here is a link to a picture of him
