Chao Khun Sri (Prayad) was a high ranking Guru monk and a close disciple of Somdej Phra Sankharaj (Pae), the Supreme Patriarch of Wat Suthat. Once Chao Khun Sri (Prayad) had created so efficacious  amulets and put them in his food bowl for blessing. Later, the supreme Patriach saw a bright radiant light emitting from the bowl. Then he admired Chao Khun Sri (Prayad)'s ability on creating such so efficacious amulets.  

Chao Khun Sri (Prayad) has given some old holy metal of the Supreme Patriach to melt with to create efficacious Tapian fish. His pair of Tapian fish has long been so great as wealth & fortune magnet but now they are becoming so rare.       

Fish in Thai culture implies abundace of food as a phrase saying " Nai Nam Mee Pla, Nai Na Mee Khao = in water there's fish while in the paddy field there's rice". Fish is also a good omen symbol of wealth in among Chinese, Teochew Chinese in Thailand will say good words for blessing " Oo Hoo, Oo Choong =  there's fish, there's abundace left". So, the fish is an important food for Chinese couple in the wedding day.  

Please notice that there is a hole at the fish's fin for inserting a thread for hanging in a shop or house, but many still like to put them in a shirt pocket. In up-country, a lot of farmers hang Tapian fish in their crop houses for good harvest and to protect insects.    

According to Thai Buddhist religious legends, before Lord Buddha enlightened, he had been born uncountable lives and practiced Bodhisattava Dhamma. Once he had been born a Tapian fish. It was legendarily told that the Bodhisattava Tapian fish was so kind, he helped protect the merchants sailing for their trade voyage and blessed them a good trading result. This is why a lot of merchants who perform waterway trade in the old times would put one Tapian fish at the front of the vessel while the other one at the back.
