I love wrasse, especially flasher and fairy wrasse. Six-line wrasse is such a curmudgeon. Without it, you can add a lot of colorful fish. See if you can remove him.
If you remove the Six-line, you can add a few of the following. All wrasse need tightly fit screen top. There are a numbers of them price from 20.00 to 2000.00 or more. I am sure seen some of these will really result in you getting wrasse fever.
Male Black Leopard, nuptial coloration. Need sand bed
Blue Flasher
Blue throat Fairy
China wrasse. Need sand bed
Ruby head Fairy
Eightline Flasher
Exquisite Fairy
McCosker Flasher. This is a very small male, color not fully developed. Full super-male is a lot more colorful.
Female Melanurus. Male is a lot more colorful. Sand bed needed
Meleagris Leopard. Sand bed needed
Naoko Fairy
Very early young male Diamond Flasher. One of the most beautiful fish there is. Look him up

These following fish can be add without removal of the Six-line

Of course no reef tank is fully stock without the Yellow Tang IMO.
