“The Pair Of Golden Fishes
These have their origins in the two sacred rivers of India the Ganges and the Yamuna. Symbolically, these rivers signify the lunar and solar channels of the human body, originating in the nostrils and carrying the alternating rhythms of breath, or chi, also known as prana. So the golden fishes bring life and happiness. They represent fertility and abundance as they multiply rapidly. Fish often swim in pairs, and in China, a pair of fish signifies conjugal fidelity and unity.
Giving a pair of fish as a wedding present is regarded as very auspicious. This signifies a fervent wish for the couple to find happiness together and be blessed with many children. The Chinese word for fish yu also means great wealth, so material prosperity is also wished for the couple.
The fish used in the symbolism here is usually the carp, which is regarded as sacred to many Asian cultures because of its beauty, its size and its long lifespan. In India and Tibet, the golden carp is regarded as being exceptionally auspicious. Even in ancient Egypt, a pair of fish is regarded as a sacred icon as it symbolizes the life – bringing waters of the River Nile. Having fish in one’s home especially in pairs is thus very auspicious.”
While originally symbolizing the rivers Ganges and Yamuna, the Golden Fish (matsya) came to represent good fortune in general, for Hindus, Jain and Buddhists. Within Buddhism it also symbolises that living beings who practice the dharma need have no fear to drown in the ocean of suffering, and can freely migrate (chose their rebirth) like fish in the water — General Symbols Buddhism
