It's a 55 with app. 90lbs. of lr. Maybe 3 to 4in. ls. The only equipment I have on it is 2 phs, a heater and a skimmer. I also have 6 fish, 1 pepp. shrimp, 1 cleaner shrimp, 2 big mushrooms and I don't have any idea about the snail population.
Not feeding the fish sounds like a good idea. I think.
I am guesstimating the move should take up to 2 hrs. The tank has to go up a flight of 8 stairs.
