What characteristic of diet is crucial for ensuring an Arowana's full spectrum of necessary nutrients over many years?

A varied diet including whole foods like shrimp or insects.

Diet composition plays a decisive role in maintaining the long-term vitality of an Asian Arowana over decades. While these fish may readily accept manufactured pellets as they grow, over-reliance on one food source is detrimental to achieving maximum lifespan potential. To ensure the necessary, comprehensive spectrum of nutrients is delivered consistently over many years, keepers must incorporate variety. This means supplementing the diet with high-quality whole foods such as appropriate-sized feeder fish, various crustaceans like shrimp, or insects, as this nutritional diversity supports organ health and immune function over the very long term.
