The Goldfish market runs along the northern section of Tung Choi Street, in the Mongkok area. Hundreds of brightly colored exotic fish species swim around tanks and hang in bags outside the shopfronts of this unique market. Of the many markets that bring colour to the streets of Hong Kong, the Goldfish Market is perhaps the most offbeat.According to Chinese tradition, fish are considered to be auspicious and believed to bestow wealth and prosperity.
