Once I have my 55 gal all set up I'm going to be doing the same thing. Where did you put the fish when you switch it out? I have a 47 gal I got for free I was going to put them in that as I worked on the tank.
I done it with the fish in, I know this is less than ideal but I was causing them more stress trying to catch them and move them to the temporary home I bought (50 Litre plastic container). They all seem unaffected so I think I was and I stress Lucky!
