I have kept a melanurus, christmas, richmond's, and leopard wrasse together sucessfully but when I tried to add a second leopard wrasse to form a pair the original leopard wrasse would not quite picking on it. It's worth a shot but be prepared to remove him from the tank if they do not get along...Currently I have 13 different wrasses coexisting peacefully in my 240g so it's do-able but not easy...
