When upgrading a tank, what would be the best way to move the live rock, corals, and fish? Do you try to aquascape the new tank or do you just keep you old aquascape and add rocks. I'm planning on upgrading my tank in the near future, and would like to know how others have handled this. FYI this would be from a 40 breeder to hopefully a tank that is 4 to 5 feet long, 20 winches wide, and 22 inches high.
