The fish is highly valued in Southeast Asian culture and is considered a symbol of wealth and prosperity.
Asian Arowana Behaviour and Lifestyle
The Asian Arowana is a solitary and territorial fish species. It is known for its aggressive behavior towards other fish, and even its own kind, when placed in small tanks. In the wild, Asian Arowana feed on small fish, insects, and other aquatic creatures. They are known for their jumping ability, and in the wild, they are often seen jumping out of the water to catch their prey.
Asian Arowana Reproduction and Life Cycles
The Asian Arowana is a mouth brooder, which means that the male will carry the fertilized eggs in his mouth until they hatch. The breeding process can take up to two weeks, after which the male will hold the eggs in his mouth for approximately 50 days before releasing the fry. The fry will then stay close to the male for protection until they are strong enough to fend for themselves.

In captivity, the fish's diet consists of live or frozen food, such as shrimp, crickets, and small fish. The fish requires a high-protein diet to maintain its vibrant colors and overall health.
Conclusion
The Asian Arowana is a unique and fascinating fish species with a rich evolutionary history. Its stunning appearance and aggressive behavior make it a highly sought-after fish in the aquarium trade. Despite being a symbol of wealth and prosperity, the Asian Arowana's wild populations are threatened due to overfishing and habitat loss. Efforts are being made to conserve and protect this iconic fish species to ensure its survival for future generations.
