The silver arowana is a large freshwater fish that can be traced back to the Cretaceous Period in prehistoric times. These carnivorous fish have long bodies with large scales and two barbels on the lower jaw. The silver arowana can be a challenge to care for and is not recommended for beginners.
No matter what species, arowanas are mostly kept in aquariums as solitary fish. Unless you have a very large aquarium and are planning on breeding arowana, only one fish is recommended. Since they are predators, they will eat any tankmates that will fit into their mouth!
Unfortunately, some arowanas are very picky eaters and refuse to eat anything other than live feeds.
