I had a McCoskers for awhile. Beautiful fish and very active. Always swims out in the open and wanting to be the center of attention. Ate like a hog and ate anything I put in the tank. I recently added a fairy wrasse to the tank, and the McCoskers became very aggressive. Started chasing the fairy around and beating him up, starting harassing everyone else in the tank too, and after a few days of adding the fairy, the McCoskers was psycho. He would swim the length of my 75g back and forth at fast speeds, attacking the glass at his reflection. He would just zoom all over the tank chasing my other few fish, and attacking himself in the glass. It was to the point of knocking himself silly, and swimming funny at times from banging the glass. The fairy would hide and never come out. I got tired of this, and removed him and gave him to a friend to put in his new tank. They are supposed to be a peaceful fish, so maybe this is an isolated incident. After I removed him, now my fairy wrasse comes out in the open all the time and my tank is peaceful again. I may try another one down the road as the last fish that I put in the tank, as they are really pretty.
