The arawana is a massive fish: nearly three to four feet in length. It is also able to see both underwater and above the water. It swims near the water's surface, and it has an eye that is able to see above and below. This attribute makes it a great hunter. Scientists also believe that the arawana is able to sense vibrations in the water to locate its prey.
Like the arapaima fish, the arawana fish needs to "breathe" oxygen. They have similar air bladders to the arawana, which allow them to stay near the water's surface.
Arawanas are often kept as pets in aquariums throughout the world. However, because they are very large fish, they need very special attention and extremely large tanks!
