Introduction to Asian Arowana (Red Dragon Fish)
The Asian Arowana (Scleropages formosus), commonly known as the "Red Dragon Fish," is a highly prized freshwater species native to Southeast Asia. Renowned for its vibrant red scales, majestic appearance, and cultural significance in Feng Shui, it is often called the "King of Aquarium Fish."

Key Features:

1. Appearance:

   • Metallic scales ranging from deep red to orange-red, with a long, streamlined body.
   • Whisker-like barbels near its mouth and large reflective eyes.
   • Can grow up to 90 cm (35 inches) in captivity.

2. Symbolism:

   • Considered a symbol of luck, prosperity, and power in Asian cultures.
   • Often kept in homes or businesses for Feng Shui purposes.

3. Habitat & Care:

   • Requires large aquariums (minimum 250 gallons for adults) with clean, warm water (28-30°C/82-86°F).
   • Carnivorous diet: live/frozen shrimp, insects, and small fish.
   • Sensitive to water quality; needs strong filtration and low stress environments.

4. Conservation Status:

   • Classified as endangered due to habitat loss and over-harvesting.
   • CITES-listed, requiring legal permits for international trade.

Fun Fact:
Arowanas are "mouthbrooders"—females carry fertilized eggs in their mouths until hatching!
