I currently have a 120g 6ft long tank. I am going to buy a 110g, 4ft long tank. My 120 takes up to much wall space. I only have 3 fish 2 clowns and a blue powder tang. Is the 4ft okay for a tang? I know they like swimmimg room. also while I am at it let me ask your advice on the moving process. I am getting new tile put in the house for Christmas ( thats why I am gonna change tanks now, I have to take it down anyway) My fish will have to be out of the tank for a few days maybe 5. I am going to put them in a 30g plastic tote with some of my live rock and water from the tank and a heater of course. I am also thinking of putting a hob
10 gallon filter on it for flow. Is there anything else I should do?
