Those that are raised in captivity are expected to live for as long as ten to fifteen years. When in the wild, they have a unique hunting style. They take huge leaps out of the water, somewhat like what the Great White sharks do, so as to have the ability to get to prey on low hanging branches.
Also, with help from their swim bladder, these fish have the ability to stay out of water for short periods.
Is It Beginner Friendly?

Its jawline is the most distinguishing characteristics this fish has. Most people affectionately refer to it as 'drawbridge' because of the nearly vertical nature of its mouth.
Their body contains silver scales that look pearl-like and run across their whole body. When the fish is still of tender age, the scales kind of look like they have a blueish tint.
When you view them from the side, their body appears long and sleek and upon further investigation, you'll notice that their caudal fin is almost fused to their dorsal fin.
The males are generally much more slender than their female counterparts who happen to be considerably thicker and have a much bigger anal fin as well. In terms of their growth rate, normally they start out very small (about four inches), however, they tend to grow exceptionally fast.
They'll grow two inches every month for the whole of their first year, so you'll need to ensure you provide them with enough food as well as a fish tank that has plenty of space.

When in the wild, the silver arowana can jump up to around three meters high in search of or hunting prey that is sitting on low hanging branches. If a fish tank is way too small or it's new, your arowana will most likely try to jump.
When the aquarium they've been placed in is too small, they'll try to jump their way to freedom.
