Furniture moving straps come to mind too.
Although 2 people lifting that tank as a recommendation? Maybe if the 2 were relatively good health/strong people. My father and I moved a 72"x24"x18" tank from one room to the other and that was a step by step shuffle maneuver.
While glass tanks are heavy, the biggest issue is that you can not really get much of a grip on them, you're lucky to have your finger tips under the tank but there's not much strength there except your ability to keep your fingers from collapsing, which is where furnature straps come into play. You just gotta make sure you use them correctly otherwise you could seriously cut off circulation in your arms
