1. Live Fish

Live fish are a natural and highly nutritious food source for Arowanas. They provide essential proteins and fats that mimic the Arowana's diet in the wild. Small feeder fish like guppies or minnows are ideal. However, ensure the feeder fish are healthy and free from diseases to avoid infecting your Arowana.

• Benefits: High protein, stimulates natural hunting behavior

• Caution: Avoid wild-caught fish to prevent parasites

  
  

2. Shrimp

Shrimp, both live and frozen, are excellent for Arowanas. They are rich in protein and contain important minerals like calcium and phosphorus, which support bone health. Shrimp also help enhance the fish’s coloration.

• Benefits: Nutrient-rich, improves color

• Feeding tip: Remove shells for younger Arowanas to prevent choking

  
  

3. Crickets and Insects

Crickets and other insects like mealworms are a favorite treat for many Arowana owners. These insects provide a good balance of protein and fat. They also encourage your fish to exercise their hunting skills, which is beneficial for their mental and physical health.

• Benefits: High protein, encourages natural behavior

• Feeding tip: Dust insects with vitamin supplements occasionally

  
  

4. Pellets Formulated for Arowanas

Specialized pellets designed for Arowanas offer a balanced diet with essential vitamins and minerals. These pellets are convenient and reduce the risk of introducing diseases compared to live foods. Look for pellets with high protein content (above 40%) and added nutrients like omega-3 fatty acids.

• Benefits: Balanced nutrition, easy to store and feed

• Tip: Soak pellets briefly to soften before feeding

Earthworms are a natural food source rich in protein and easy to digest. They are also a good source of iron and other trace minerals. Feeding earthworms occasionally can diversify your Arowana’s diet and provide enrichment.

• Benefits: High protein, rich in minerals

• Feeding tip: Use fresh or frozen earthworms, avoid worms from contaminated soil

  
  

6. Krill

Krill is a small crustacean packed with protein and antioxidants. It supports immune health and enhances the vibrant colors of your Arowana. Krill can be fed live, frozen, or freeze-dried, making it a versatile option.

• Benefits: Boosts immunity, improves coloration

• Feeding tip: Use as a supplement rather than staple food

  
  

7. Small Frogs or Tadpoles

In the wild, Arowanas consume amphibians like frogs and tadpoles. These provide a rich source of protein and fats. Feeding small, disease-free frogs or tadpoles occasionally can mimic their natural diet and support growth.

• Benefits: Natural diet component, high protein

• Caution: Ensure frogs are captive-bred and free of toxins

  
  

8. Beef Heart

Beef heart is a popular choice among Arowana keepers for its high protein and fat content. It promotes rapid growth and muscle development. However, it should be fed sparingly due to its richness and potential to pollute the tank water.

• Benefits: High protein and fat, supports growth

• Feeding tip: Cut into small pieces and feed occasionally

  
  

9. Silkworm Pupae

Silkworm pupae are nutrient-dense and easy to digest. They contain essential amino acids and fatty acids that support overall health and coloration. Many Arowana owners use silkworm pupae as a treat or supplement.

• Benefits: Rich in nutrients, enhances color

• Feeding tip: Feed fresh or freeze-dried pupae

  
  

10. Frozen Bloodworms

Bloodworms are a convenient and nutritious food option. They are high in protein and stimulate feeding response due to their bright red color and movement when thawed. Frozen bloodworms are safer than live ones, reducing disease risk.

• Benefits: High protein, easy to store

• Feeding tip: Thaw before feeding and avoid overfeeding

• Supplement vitamins: Occasionally add vitamin supplements to boost immunity.

• Monitor health: Watch for signs of digestive issues or changes in appetite.
