Oriongirl brings up a very good point about the tang. Yellow Tangs show stress very early on if the problem is water quality. They are sort of like mineshaft canaries, in that if you see anything wrong with the Tang, it will likely affect the others soon. If your tang is eating well, grazing on tank algae, and brightly colored (no pale whitish spots) than your water quality is fine.
It is good that you have created a lot of caves and hiding spots for your fish. That is keeping fights to a minimum. Also, I wouldn't worry about the cleanup crew right now, 50 hermits is definately sufficient. If you begin to see their numbers decline, then you should think about adding more, perhaps some scarlet hermits or a mithrax crab.
