In older times, the two fish were drawn to symbolize the Ganges and the Yamuna rivers. It has, through interpretation, come to mean luck and fortune. It also means the courage and fearlessness to face the ocean of sufferings and to be able to swim freely like fish through water.

In Buddhism the golden fishes represent happiness and impulsiveness, as they have complete liberty of movement in the water. They epitomize fertility and profusion, as they multiply very rapidly. They embody freedom from the fetters of caste and status, as they mingle and touch readily. Fish often swim in pairs, and in China a pair of fishes symbolize conjugal harmony and loyalty, with a brace of fishes being traditionally given as a wedding present.
