Arowana Fish Tank Setup
Arowanas are big, active fish that need plenty of space to thrive. Here’s how to set up the perfect home for them:
- Minimum Tank Size: Arowanas can grow up to 3 feet, so start with at least a 300-gallon tank (6×3.5 feet). For adults, 400-800 gallons is ideal to accommodate their size and swimming habits.
- Secure Lid: These fish are famous jumpers, capable of leaping 6 feet to catch prey or probably escape. So a sturdy, tight-fitting lid is non-negotiable.
- Decor: Keep it minimal. Use smooth rocks or driftwood to mimic their natural habitat, but avoid sharp objects that could injure their scales. Leave ample open space for swimming.
We offer tank recommendations and accessories to ensure your Arowana’s setup is just right. A well-designed tank not only keeps your fish happy but also showcases their elegance.

Water Parameters
Water quality is critical for Arowana health. These fish are sensitive to changes, so consistency is key:
- Temperature: Maintain 75-86°F (24-30°C), depending on the type (e.g., Asian Arowanas prefer the warmer end).
- pH Level: Aim for 6.0-7.0, slightly acidic to neutral, to match their natural environments.
- Water Hardness: Keep it soft to moderately hard (5-12 dGH).
- Filtration: A powerful canister filter is essential to handle waste from their meaty diet. Perform 25-30% water changes weekly to keep ammonia, nitrites (0 ppm), and nitrates (40 ppm) in check.
Test your water regularly with a kit vailable through Arowana Fish Sale to catch any issues early. Clean, stable water means a stress-free fish and fewer health problems down the line.
Diet and Feeding
Arowanas are carnivores with hearty appetites. Feeding them properly keeps them growing strong and colorful:
- Food Options: Offer a mix of live or frozen foods like brine shrimp, worms, small fish (e.g., guppies), and Insects. As they grow, add larger prey like shrimp or chunks of fish.
- Feeding Schedule: Juveniles need 2-3 small meals daily; adults can eat once every other day. And it’s important to avoid overfeeding to prevent obesity and water pollution.
- Variety: Rotate foods to ensure balanced nutrition. High-quality pellets designed for carnivorous fish can supplement their diet.
