for the hijacker, generaly, as long as only one fairy is a male, best to have with a few females...a fairy and Y coris, generaly yes.
Right; this is a huge group of fish, even includes hogfish, tusk fish, etc. I'd think two wrasse of completely different shapes are fine--assuming they have enough room. I have a harlequin tusk & a Scott's Fairy wrasse together and they're fine. (They're both the Australian variety). No real rule on this, IMO, depends a lot on the individual fish.
