Also thinking of a Blue star Leopard wrasse as well, but they are bad at shipping and even harder to get thru QT because of the shipping issue.They're gorgeous fish, I don't see why you couldn't. Your tank is big enough and you have the filtration to add more fish. Plus, they sleep in the sand, so they shouldn't bother with another fish's territory within the rockwork (assumption). lol, I don't know why I want you to add more wrasses haha. It's as if I'm viewing your tank as mine. It just shows how hobbyists care about another's tank, sometimes to a fault ;Writing.
I love wrasses because of the personality of my late Pintail, so who wouldn't want a ton of wrasses, LOL!!! ;Hilarious
