my thats quite the collection
I think you'd probably have to check on which genus they're from. Even though you have a big tank some wrasses that are from the same genus tend to have problems with one another, esp if they have the same shape or coloring. I have heard that fairy wrasses, being more docile, are easier to keep together than some other wrasses but this info isn't from my experience just from what I've been reading (I love wrasses too

).
