I agree. The lighting in the picture isn't real good. You're tank looks like it is still cycling though. You need to get readings of 0 ammonia and 0 nitrite. Once those both reach zero do a 50-60% pwc
and then you can add the fish. The ywg and pistol shrimp should be fine to add first once the tank is cycled. I'd add maybe only 5 hermits to start with. They feed on algae and pick at the rocks so you want to make sure there is enough for them to eat. Since the tank is brand new there may not be a plentiful food source to support 10 hermits all at once. Also make sure that you have some empty shells for the hermits to grow into.
. Just remember, the more patient you can be with adding the things the better off your tank will be. Saltwater livestock can be spendy. Go slow and you will greatly reduce your chance of losing stock. I'd wait a week and then test the water again.
