Moved my big guy in a large rubbermaid container. No air pump, over 3 hours, no problem. My only suggestion is to get bungee straps to hold the lid on.
Well guys we picked it up. ITs a Nice looking fish too. Picked it up in a Big Rubber tub for about a 1hr and half ride no pump. It was good the whole ride home and is now safe in the pond having fun.
