Tank Setup

Black Arowanas need a very large tank. A minimum of two hundred gallons is recommended for a young fish and even larger space is needed as it grows. They prefer water temperatures between seventy five and eighty two degrees Fahrenheit with neutral pH levels. The tank should have a tight cover because these fish can leap with great force. Decorations should be simple to avoid injury with plenty of open swimming space. Strong filtration is important due to their size and appetite.

Diet and Feeding

Black Arowanas are carnivores and enjoy a varied diet. They can eat pellets shrimp fish insects worms and other meaty foods. Young fish should be fed smaller meals more often while adults can be fed once a day or every other day. A balanced diet helps them maintain good growth and strong coloration.

Behavior

Black Arowanas are calm graceful and alert. They typically swim near the surface and may display territorial behavior in smaller tanks. They can be jumpy when startled but become more comfortable with stable surroundings. These fish are best kept alone because they may fight with other arowanas unless the tank is extremely large.

Tank Mates
