I am adding a rear hanging protien skimmer to my 55FO and don't have enough clearance. I need to move the tank out away from the wall apx. 4". I have a wooden cabinet stand and a carpeted floor. Should I remove all water and critters into another container make the move and put them back or can I remove all but about 5" or so of water, leave the fish, move the tank and replace the water. The later would seem less stressful than catching the fish and I would have some help moving the tank. Any suggestions or comments would help. Thanks, Steve
