Title: An Introduction to the Golden Dragonfish

The golden dragonfish, also known as the beautiful hard-bone tongue fish (scientific name: Scleropages formosus), is a type of ancient freshwater fish. It is native to rivers and lakes in Malaysia, Indonesia, and Sumatra. The adult fish can reach a body length of 40-50 cm and has a lifespan of several decades. It has a fierce temperament and mainly preys on live fish, shrimp, water insects, and frogs.

Since the mid-20th century, the golden dragonfish has been developed as an ornamental fish. It has gained attention for its metallic luster like armor and its bright colors, as well as its imposing demeanor. Its value has risen to tens of thousands of dollars, making it one of the most prestigious ornamental fish. The golden dragonfish has been protected under the Washington Convention (CITES) due to over-exploitation, listed in Appendix I.

There are several varieties of golden dragonfish, including red dragonfish, green dragonfish, belly golden dragonfish, high-back golden dragonfish, and more. Each variety has unique characteristics and colors. For example, the young Southeast Asian red dragonfish has small red scales, while the adult fish have deep red gill covers and pinkish-purple scales that shimmer.

The golden dragonfish is a fascinating creature with a triangular head, golden armor-like scales, and a large mouth. It is known for its unique breeding behavior, where the male fish guards the eggs and孵化 until the young fish hatch. This has earned it the nickname "dragon spitting pearls."

In conclusion, the golden dragonfish is a rare and precious ornamental fish with a long history and unique characteristics. It is not only a symbol of wealth and status but also an excellent example of the beauty and diversity of nature's aquatic creatures.
