How to Raise Arowana Fish Arowana are extremely interesting fish. Lots of people who raise Arowana as pets, choose the silver Arowana fish. In the end, folklore says that owning an Arowana can bring about good fortune and ward off evil spirits. Sounds like great reasons to me for owning one of those fish. The fish is exceptional looking, elongated with a body that is covered in silvery scales. The fish is also famous for its short head and rigid jaw. This fish is found in many parts of the world such as South America, parts of Africa, Vietnam, Australia, and Asia, to name a few. Although the Arowana is a very pretty fish, it’s very much a predator. In the wild, the Arowana eats other fish, insects, and even birds. Since the fish has the ability to literally jump out of the water, it may snag animals off of low hanging tree branches and brush. As pets, this fish is known for frequently jumping from their fish tanks. This especially happens when they’re spooked by loud noises and other disturbances. Also, because of the fish’s aggressive nature, it’s famous for eating tank mates and even attacking other Arowana. In other words, it is hard for these guys to make friends in the fish tank. Not only are these fish hard themselves, they’re also tough to raise at home. To raise these fish by yourself, you want a very large tank. Most experts recommend a fish tank that is at least 250 gallons. That is because a full-grown Arowana can get to 47 inches long. And having a small tank wouldn’t allow them to float around and turn as needed. Moreover, the water, like with any fish tank, needs to be at just the right temperature and have the correct pH. For Arowana, the temperature should be between 75 and 86 degrees Fahrenheit (24-30 C) and the pH should be kept between 6.5 and 7.5. Since the fish is so aggressive, adding additional fish to the fish tank can be tricky. However, it is likely to find tank mates for the fish. For example, sometimes Oscars, Jack Dempsey fish, and catfish can get the job done. Having said that, there is absolutely no guarantee because of the aggressive nature of the fish. The Silver Arowana can be difficult to increase in the home, proper care is vital to be successful. However, increasing them can also be a very rewarding hobby.
