There are many wrasses that can be kept together. The fairies and possum wrasse are two that can. Some will actually school, so I would not say never. Problems with agression are common with the six and eight lines, which is what most people have. I would watch ANY new addition no matter what species, as all present tank mates will have their own territorries.
