Name: Silver Arowana Max Size: Up to 36 inches (90 cm) Recommend pH: 6.0-7.5 Recommended Temperature (°F): 75-82°F (24-28°C) Diet: Silver Arowanas are carnivorous and primarily feed on small fish, insects, and crustaceans in their natural habitat. In the aquarium, they should be offered a varied diet that includes high-quality pellets, frozen or live foods such as small fish, shrimp, crickets, and worms. Providing a balanced diet is essential for their health and growth. Temperament: Silver Arowanas are predatory fish and can be aggressive towards smaller tank mates. They are best suited for large, species-specific aquariums or with other large, aggressive fish. Due to their size and territorial nature, it is important to provide ample space and hiding places to reduce stress and potential aggression. Schooling or Non-Schooling Fish: Silver Arowanas are non-schooling fish. They are solitary by nature and prefer to swim alone in their territory. Possible types of tank mates: Silver Arowanas are best kept with other large, aggressive fish that can withstand their territorial behavior. Tank mates may include large cichlids, catfish, and other similarly sized predatory fish. Avoid keeping them with small or peaceful fish that may become prey or targets of aggression. Behavior: Silver Arowanas are known for their sleek, silver-colored body and impressive size. They have a long, streamlined shape and powerful jaws, which they use to capture their prey. These fish are skilled jumpers and are known to leap out of the water to catch insects or small prey. In the aquarium, it is important to provide a tight-fitting lid or cover to prevent them from escaping. Silver Arowanas are also known for their intelligence and curious nature. They may interact with their owners and exhibit interesting behaviors like surface gulping or "playing dead" to ambush prey. Fun Fact: Silver Arowanas are renowned for their unique ability to breathe air using a specialized organ called the labyrinth organ. This adaptation allows them to extract oxygen from the air at the water's surface, enabling them to survive in oxygen-depleted environments or even out of water for short periods. It is fascinating to observe their occasional jumps to the water's surface to gulp air, which is an essential part of their natural behavior.
