I would go bigger, 75 gallon, I'm in East Harlem and its going well with a 120 gallon. I moved it from the Bronx to here and it wasn't that bad. Your move is a 3 gallon so you'll be fine, just keep all the water so parameters don't swing much. I have a busy work schedule but my tank gives me...
You can also buy from places that quarantine for you, i use dr quarantine. I just dont have the space for a qt since my tank is located at my office. cost a little more but worth the peace of mind
