The two that concern me on this are the Mandarin and the Pygmy. That size tank isn't going to be enough to support the mandarin. They are notoriously picky eaters and need a HUGE pod population to support them. Unfortunately tons of them die because places will tell you they only need 30g, which is more based on their size and swimming habits. Unless you are going to be running pod farms on the side, I would steer clear.
The pygmy is the other slight concern. They are darty little fish and like to have room to explode in speed and swim. They do alright in biocubes and nanos, but definitely not the preferred environment. If possibly minimize your LR in the display side to allow the most open water for swimming. Not enough room to swim might cause certain dwarfs to pick at soft corals or be aggressive.
Also, make sure you have enough sand for the BSG to burrow and be happy, and double check your rock is secure on the bottom of the tank to prevent cave ins and death.
HTH.
