I just moved my 75 gal tank, What a hassel, I put all the rock in buckets and filled them with water, Then I placed the fish in a cooler, also about another 25 gals of water in buckets. As soon as I got the tank moved I put in the rock and the inverts. I added what water I saved and started making more. I kept the fish in the cooler which I put an air stone and a heater in, The next morning my trigger and grouper had passed. My puffer made it barely but hasn't eaten in 3 week, not one bite. All inverts made it.
