I would hesitate on the emerald crab personally. Flip the red leg hermit for a dwarf red tip. They are less aggresive, and don't grow as big. Just make sure with any hermit you have extra shells scattered across your tank. Other then that go for it !

For what you want to (from what I understand) 7.0 megapixles should do it.
