Silver Arowana

Tank mates must be chosen cautiously due to their predatory nature. Large, robust fish are suitable, but smaller fish may be eaten. Avoid aggressive species that may injure the Arowana. Maintain a large tank to reduce territorial disputes. Provide hiding spaces for compatible species to retreat. Introduce all fish simultaneously to reduce aggression. Observe interactions carefully to prevent bullying or stress. Overstocking can lead to injuries and poor water quality. Avoid tank mates with delicate fins susceptible to nipping. Regular monitoring ensures a stable and safe environment.

Silver Arowanas require very large aquariums of at least 500 liters. They are top predators and need strong filtration to handle their bio-load. Provide a secure lid to prevent jumping, as they are strong jumpers. Maintain water temperature between 24°C and 28°C for optimal health. pH should be slightly acidic to neutral, between 6.0 and 7.5. They prefer soft to moderately hard water for comfort. Decorate minimally to allow ample swimming space. Regular water changes of 30% weekly are recommended. Monitor water parameters closely to avoid stress or disease. Arowanas are sensitive to poor water conditions, which can reduce lifespan.

Silver Arowanas are carnivorous and require high-protein diets. Feed live or frozen fish, shrimp, and insects as staple foods. Pellets formulated for carnivorous fish can supplement natural diet. Feed twice daily in amounts the fish can consume within 5 minutes. Avoid overfeeding to prevent obesity and maintain water quality. Occasionally provide variety with crickets or small amphibians. Observe feeding behavior to ensure all fish receive adequate nutrition. Remove uneaten food promptly to prevent contamination. Adjust feeding as the fish grows and metabolism changes. Monitor for signs of deficiency or abnormal behavior.

Breeding Silver Arowanas is challenging in captivity. Pairs form naturally but require large, specialized tanks. Maintain optimal water conditions with temperatures around 26°C. The male carries fertilized eggs in his mouth for protection. Provide floating plants and calm water to encourage spawning. Feed conditioning diets high in protein for successful reproduction. Observe parental behavior closely to prevent stress. Fry should be fed tiny live foods initially. Gradually transition fry to larger prey as they grow. Monitor water quality and temperature closely for survival.
