Pick my next fish

[sitandwatch]

I am getting the add a fish vibes but have no real idea what I want and when I find something cool at Red Coral I get that "bad idea" look.

So looking for suggestions on a cool next fish to add.

Current stock
Pink Tail Trigger
Niger Trigger
Blue jaw Trigger
Dusky Wrasse
Yellow Tang
Two sand sifting golbies
Pair of true perc's

I am thinking of a mystery wrasse myself.

Thanks
