You should probably rehome both of them until your tank is very mature. A new 32g tank will not have enough food in the sand for one diamond goby, let alone two. If you decide to keep one, you will need to supplement his diet and ensure he is actually getting the food you are giving specifically for him or else he will slowly starve.
