I have an unknown wrasse (its solid pink), a blue sided fairy wrasse and a mccoskers wrasse in a 60 gallon shallow reef. There was a lubbocks wrasse as well until I had a nitrate spike and I lost that one. I tried to introduce a new lubbocks and they did not accept it. But the 3 of them get along very well and with the other fish in the tank. What ever the pink one is, is the one that killed the new lubbocks when I added it.
