The original writeup as below:
Asian arowana (Scleropages Formosus), as the name implies is found exclusive in Asia and has the reputation as being the world's most expensive freshwater aquarium fish.
The reason for this is because of its close resemblance of the oriental dragon and hence highly prized. In Chinese traditions and cultures, the oriental dragon is a symbol of good luck, strength and power and is believed to ward off evil.
Ancient Chinese emperors were also obsessed with dragons and their robes were embroidered with dragons. Dragons were therefore considered auspicious.
Many businessmen also believed that keeping an arowana will make their businesses prosper. In fact, the arowana is commonly known as the Dragon Fish because of the 2 barbels.
When the arowana glides through the water, its pectoral fins often spreads out, resembling a dragon in full flight. While you may have seen a dragon in books or posters, you may wonder what the terms barbels or pectoral fins meant.
The below illustration is specially designed to help you understand the parts of the asian arowana.
