I used to have an enormous pickle jug that I kept fish in. I was never one to go for "normal" fish tanks. In it I had a nice little variety of fresh water fish including a smallish school of neons(About 10 or 12), a pair of leopard angel fish, a beautiful spotted shark, 2 African clawed frogs that I actually got to breed, and one lonely little catfish that got enormously fat on all the detritus left by the others. I was heart broken when the jug developed a crack in the side. I had to give them all up but I ended up selling the jug crack and all for 75 bucks.
