When I bought fish back in the early 70s, they put them in Chinese-take-out type containers. They would start to leak after a while.
I remember buying Black Tetras from Hess's (original store) in downtown Allentown, PA. I was around 15 and walked 8 miles to the store. By the time I got home, most of the water had leaked out. The fish were floppy around in about an inch of water. It was winter time, so the water was very cold. I dropped them right into the tank; no acclimation period. Amazingly they survived.
