Origin:
Native to the rivers and floodplains of the Amazon Basin in South America, the Silver Arowana thrives in slow-moving waters surrounded by dense vegetation. Its natural habitat supports its predatory behavior and active swimming needs.

Diet:
As a carnivorous predator, the Silver Arowana requires a protein-rich diet to maintain health and energy. Feed it a variety of live or frozen foods such as shrimp, small fish, insects, and worms.

Tank Mates:
Choosing tank mates for the Silver Arowana requires careful consideration due to its size and predatory nature. Compatible companions include large, peaceful fish such as plecos, large catfish, and some cichlids. Avoid small fish, as they are likely to be mistaken for prey, as well as overly aggressive species that may stress the Arowana.
