I have an African Leopard Wrasse. She's a beauty. The only thing that makes leopard wrasses "expert only" is feeding in captivity. When you go to LFS
just ask them to feed it. If it eats then get it. It will be no different than any other fish with one exception. It needs live sand as it sleeps underneath it.
I had a fairly large Solar Fairy Wrasse in my 40 breeder and my Leopard Wrasse did not like him. So I traded the Fairy Wrasse to my LFS
. The point is having more than one wrasse can be an issue. However, your tank is larger than mine and things might be different.
