Silver arowana Facts
Silver arowana is freshwater fish that belongs to the family bonytongues. It can be found in the Rupununi and Oyapock rivers in South America and in Amazon Basin. Silver arowana also inhabits floodplains and swamps with slow-flowing water. This fish can be also seen in aquariums around the world because of its unusual, beautifully colored body. Silver arowana represents important source of food for the local community. Uncontrolled collecting from the wild (due to pet trade) is another factor which decreases number of silver arowanas in the wild. Luckily, population of silver arowanas is still large and stable.
