The rocks’ placement should allow ample swimming space, preventing crowding while maintaining interest in different areas.

Regularly cleaning textured rocks prevents buildup of debris and ensures your arowana interacts with a healthy environment.

Hanging Ornaments

Hanging ornaments provide vertical interest and interactive opportunities for arowanas.

These decorations add height to the tank and mimic natural elements like overhanging branches or roots. Arowanas can swim beneath or around them, using the spaces for exploration. Lightweight ornaments that hang from the tank lid or decorations attached to driftwood can create dynamic swim areas without obstructing movement. Some arowanas may investigate the ornaments repeatedly, showing curiosity and engagement. Hanging ornaments also cast shadows, providing visual contrast and a more stimulating environment. Proper placement ensures they don’t interfere with filtration or water flow while maintaining safety.

Using multiple hanging ornaments in different parts of the tank encourages activity and exploration. Combining textures, shapes, and positions creates an enriched environment that reduces stress. Ornaments with natural colors blend seamlessly with rocks, driftwood, and plants, enhancing the overall tank aesthetics. Over time, algae and microfauna growth on these surfaces may provide additional enrichment and minor food sources. Careful arrangement ensures the tank remains visually balanced and prevents overcrowding. Hanging ornaments can also influence swimming patterns, guiding the arowana to explore upper, middle, and lower areas of the aquarium. Rotating or slightly adjusting ornaments periodically can renew interest and stimulate natural curiosity, maintaining engagement over time.

Mirror Panels

Mirror panels can encourage arowanas to explore their own reflection, providing mental stimulation and mild exercise. They should be used sparingly to avoid stress.

Placing a small mirror on one side of the tank lets your fish interact briefly, which can reduce boredom. Monitor their behavior to ensure they remain calm and adjust placement if needed.

Ceramic Caves

Ceramic caves offer secure hiding spaces and a sense of territory for arowanas. Their smooth surfaces are safe for the fish while providing natural-feeling shelter.

Arranging multiple caves of different sizes encourages exploration and varied swimming patterns. Arowanas may retreat into the caves when resting or avoiding bright light. Proper spacing ensures the tank doesn’t feel cramped and allows water to circulate freely. Caves can also be positioned near driftwood or plants to enhance naturalistic areas. Over time, your arowana may develop favorite spots within the caves, showing comfort and engagement with the tank’s layout.
