Arowanaincludes arowana species
The Arowana is a long, sleek streamlined fish of great beauty with a unique character. Arowana are large and often aggressive with the potential of rapid growth. Many believe that Arowanas bring good luck and fortune.
A well-balanced Arowana diet consists of:
- Provide pellets designed for surface feeding carnivorous fish.
- Live or frozen fish and insects, krill, worms and shrimp.
- Avoid insects or inverts with sharp or very hard shells for juvenile Arowanas.
Things to remember when feeding your arowana:
- These fish are surface feeders often gliding just below the water surface.
- Feed young fish 2-3 times a day, adults once a day; feed only what they can eat in 1 to 2 minutes.
- Thaw frozen foods before feeding.
- Keep in an appropriately sized aquarium; the arowana is a surface-swimming fish, so width and length of the tank are more important than height. Arowanas are avid jumpers, so be sure to have a tight-fitting aquarium hood. Arowanas are more sensitive to nitrites than other fish, so provide proper filtration and perform 10 to 20% water changes as needed.
- Stable water quality and parameters are critical to the health of aquatic life. If you are unsure of your water quality, Petco provides free water testing.
- Arowana have mandibular barbels or whiskers that are used to sense movement on the water surface.
- Known for jumping out of tanks that do not have a secure top; in the wild Arowanas will jump out of the water to grab prey.
- Daily: check filter, water temperature and other equipment.
- Weekly: check water quality at least once a week.
- Monthly: change 10 to 20% of the total volume of water every week if necessary. Otherwise, change 25% of the total volume of water every 2 to 4 weeks.
- Adult Arowanas are best kept alone, because of their size and requirements. If housed with other tank mates they must be large enough not to be swallowed whole by the Arowana and must not occupy the upper section of the tank. Most bottom dwellers are tolerated; other aggressive fish may ruin the long flowing fins of the Arowana.
