This replicates the dry season, the onset of breeding. After a week or two, gradually raise the water level to replicate the rainy season.
When conditions are right, the female will lay eggs. Silver Arowanas are paternal mouthbrooders, meaning the male will keep the fertilized eggs in his mouth, protecting and nurturing them until they hatch. Remember these key points about Arowana breeding:
- Ensure both male and female Arowanas are present
- Set up a separate breeding tank with stable water parameters
- Replicate the natural water conditions of the dry and rainy seasons
- Understand that the male Arowana is responsible for mouthbrooding
Note: Breeding Silver Arowanas is not a task for those new to the hobby. Attempting to breed Arowanas without the necessary experience and knowledge can lead to stress and poor health for the fish. It is advised to gain experience in keeping Arowanas before attempting to breed them.
Properly caring for your Silver Arowana can be a rewarding and fulfilling experience, even for beginners. With the right supplies, tank setup, and attention to their unique needs, these beautiful fish can thrive in your home aquarium.
