Yes, arowana are highly capable jumpers and will frequently jump out of a pond or aquarium if given the opportunity. This behavior is a natural part of their predatory instincts and survival mechanisms. They are known for their impressive agility, with silver arowana, for instance, able to leap as high as four feet out of the water.
Why Do Arowana Jump?
Arowana are apex predators in their natural habitats, and their jumping behavior serves several key purposes:
- Hunting Prey: In the wild, arowana often jump to catch insects, small birds, or other animals perched on overhanging branches or leaves above the water surface. This makes them opportunistic feeders.
- Escaping Predators: While they are top predators themselves, smaller or younger arowana might jump to escape larger fish or other aquatic threats.
- Natural Instinct: Jumping is an ingrained behavior, a fundamental part of their natural activity pattern, even in a captive environment where food is readily available and threats are minimal.
- Stress or Poor Water Quality: In some cases, arowana might jump due to stress, poor water conditions, or an unsuitable environment, attempting to escape perceived discomfort.
Preventing Arowana Jumps in Ponds
Given their strong jumping ability, it's crucial for arowana owners to take precautions to prevent them from leaping out of their aquatic environments.
Here are practical solutions and considerations for ponds:
- Secure Pond Covering: The most effective way to prevent jumping is to ensure your pond has a sturdy and secure cover. This can be a tight-fitting net, a mesh screen, or a solid lid that can withstand the force of a jumping fish. Ensure there are no gaps or openings large enough for the fish to escape.
- Maintain Appropriate Water Levels: While a cover is paramount, some owners opt to keep the water level a few inches below the rim of the pond to create a buffer, reducing the likelihood of a successful jump over the edge.
- Provide Ample Space: Ensure your pond is adequately sized for arowana, as cramped conditions can lead to stress and an increased likelihood of escape attempts. A larger, more naturalistic environment can help reduce stress.
- Stable Environment: Maintain optimal water quality (temperature, pH, ammonia, nitrite, nitrate levels) and ensure the environment is free from sudden loud noises or disturbances that could startle the fish.
- Submerged Decorations: Avoid tall decorations or plants near the water surface that could provide a launching point or an incentive for the fish to jump towards.
Understanding Arowana Behavior
Arowana are fascinating fish, known for their prehistoric appearance and active nature. Their strong musculature and agile bodies are perfectly adapted for rapid, powerful movements, including vertical leaps. This makes them captivating to observe but also requires careful consideration of their environment to ensure their safety and well-being. Recognizing their natural tendencies, such as jumping, is key to providing them with a suitable and secure habitat.
