They also contribute to the aesthetic appeal of the aquarium, blending functionality with natural beauty. Properly sized and strategically placed, natural shelters allow Arowanas to feel confident while moving through their environment.

Choosing the right materials for hiding spots is important to prevent sharp edges or unstable structures. Driftwood should be treated to remove toxins, while rocks must be smooth and securely positioned. Plants can complement these shelters, adding softness and coverage without restricting swimming paths. Arowanas gradually learn to use these spots consistently, showing calmer movements and less stress-related behavior. By creating a balanced combination of open areas and secure hiding places, you ensure your fish experiences both safety and freedom, resulting in a healthier, more relaxed aquarium environment.

Gentle Water Flow

Arowanas prefer calm water, so gentle water flow can reduce stress. Strong currents make them swim excessively, causing fatigue and anxiety. Adjusting the filter output or using flow-reducing devices helps maintain a stable, comfortable environment.

Gentle water movement also improves oxygen circulation without creating turbulence. It allows the fish to navigate easily, rest, and feed without struggling against strong currents. Maintaining this balance promotes overall well-being and reduces the likelihood of stress-related behaviors.

Tank Background

Adding a tank background can minimize visual disturbances from outside the aquarium. Solid or natural-colored backgrounds limit reflections and shadows, giving Arowanas a consistent sense of security. Properly placed, backgrounds create a calming environment that supports mental stability and reduces startle responses.

Floating Shelters

Floating shelters provide temporary cover for Arowanas during feeding or exploration. They allow the fish to retreat quickly, lowering stress and encouraging natural behavior.

Soft Substrate

Using a soft substrate reduces injury risk and creates a more comfortable tank floor. Materials like fine sand or smooth gravel are ideal, providing safe surfaces while enhancing the tank’s natural appearance.
