The Arowana, often called the "Dragon Fish," is a premier highlight within the Bueng Boraphet Aquarium. Characterized by its elongated body, large metallic scales, and distinctive barbels resembling the mythical Chinese dragon, it is revered as a symbol of wealth, luck, and authority. Ecologically, the Arowana is an ancient freshwater fish with an evolutionary lineage dating back to prehistoric times. Its presence in Nakhon Sawan perfectly aligns with the city's "Dragon City" identity, seamlessly bridging cultural beliefs with the natural wonders of the river basin.
