Apparently there’s a big market out there for goldfish!  Actually, being the nerd that I am, I checked into it and many Vietnamese people practice feng shui, the traditional Chinese art of designing buildings and rooms for good energy flow. In the feng shui system, the five elements (water, wood, metal, fire and earth) should be balanced. Live animals like goldfish represent fire and can add balance to the home, so fishtanks are quite common in the Vietnamese home.
