yes it will reduce the fish list that you will be able to keep !! i just moved a 55gal. reef last Feb. (didn't lose 1 thing). but i moved ALL of my water too. the next time we move (to a house) i have to move a 125gal. reef from the second floor. that is going to suck !!
i suggest taking all of your water with you. and getting some of the styrofoam boxes that your LFS has things shipped in. you can use these to house your fish and corals while the move is going on !!
