IMO, you are setting yourself up for failure. All of the fish will be too large for the tank, and certainly for the filtration.
you WILL NOT calm the lunare wrasse, which will likely bully all the others. In all likelihood you will have an ick problem with the tang. Lunare wrasse have been known to have strange quirks - I cared for one in a several thousand gallon system that would methodically eat the eyes out of all yellow tangs.
I would encourage you to STRONGLY reconsider this stocking.
