How to know arowana mail and femail

Arowana, also known as Dragon Fish, are a popular species of fish kept as pets. Determining the sex of an Arowana can be challenging, but here are some methods to help you identify the male and female:

Visual Inspection:

  1. Body shape: Males tend to have a more slender and elongated body shape, while females are generally more rounded and fuller.
  2. Fin shape: Males have longer and more pointed fins, especially the dorsal fin, while females have shorter and more rounded fins.
  3. Coloration: Males often have more vibrant and intense coloration, especially on their fins and tail, while females tend to have more subdued colors.
  4. Scales: Males may have more prominent scales on their belly, while females may have fewer or smaller scales.

Behavioral Observations:

  1. Courtship behavior: Males will often display courtship behavior, such as swimming in a circular motion, vibrating their fins, or releasing sperm-like milt, to attract females.
  2. Aggressive behavior: Males may become more aggressive during breeding season, while females tend to be more docile.
  3. Nesting behavior: Males will often build a nest using plants or other materials, while females will lay their eggs in the nest.

Other Methods:

  1. Genetic testing: Some breeders use genetic testing to determine the sex of their Arowana. This involves taking a fin clip or blood sample and analyzing the DNA.
  2. X-ray: Some breeders use X-ray to examine the internal organs of the fish, which can help determine the sex.

Important Notes:

By combining these methods, you may be able to determine the sex of your Arowana. However, if you're still unsure, it's always best to consult with an experienced breeder or aquarium expert.
