Arowanas should be fed floating pellets or sticks designed for surface-feeding, carnivorous fish, as well as live, frozen, or freeze-dried fish, insects, krill, worms, and shrimp .
Due to arowana's skittish nature, they need plenty of space without sudden movements or bright lights. Tolerant to changing conditions, you should aim to maintain your water temperature around 24°C- 28°C ( 75 - 82 degrees) with pH levels of 6.5. - 7.5.
