The Arowana is the staple fish of the high-end aquarium. Its illustrious colors and striking size provides it with a magnificent presence which lives up to its legendary reputation.
It is widely believed in Asian cultures that Arowana fish will bring luck, fortune and prosperity to its owners. Even if you don’t believe in superstition, if you have the ability to house a fish which requires an extremely complex care cycle then your chance of inheriting good fortune is very high.
Raising Arowana fish requires a great amount of care and investment. Arowana’s can live up to 20 years, a long-lived beautiful specimen that will be worthy of good investment.
“Arowana” is a common term addressing 7 species of the ancient fish order “bony tongues” – named after the bony plates on the floor of their mouths. This plate is opposite the teeth on the roof of the mouth, pressing against the teeth when food is eaten.
Arowanas can be found in tropical regions around in world, Africa, Asia, South America and Australia. The world’s largest freshwater fish, Arowana Gigas, lives in the South American Amazon growing up to 5 metres long.
The most commonly kept pet species is the Osteoglossum bicirrhosum (South American Arowana) whereas the most impressive looking Arowana is accepted to be the Asian Arowana, also known as the “Dragon Fish” (Scleropages Formosus). In Chinese mythology, the Dragon Fish is a creature which can bring good luck and ward off evil.
Both Asian and South American Arowana species have large barbels on their bottom lips to help detect prey wiggling at the surface. Arowanas are mouthbrooders which carry their eggs in their mouth to prevent their eggs from being eaten by predators. Mouthbrooding occurs in male South American Arowanas and female dragon fish.
Once Arowana fry have reached a decent size, they are released from the mouth to fend for themselves.
A large aquarium is essential for keeping Arowanas because they are a very big and active fish requiring a high volume of water to match. The Dragon fish can grow up to a yard (metre) in length, its important that the fish tank is around 2 yards (1.8 metres) long.
The Arowana is a surface-feeding carnivorous fish. We recommend using specialized Arowana pellets, these have been specially crafted to ensure your fish receive the optimal amount of nutrients.
It is also advisable that the diet is kept varied and live food is provided occasionally. Insects, krill, blood worms and shrimp will work.
Especially when feeding young Arowana fish, avoid food with sharp edges, such as frozen foods and insects with hard shells – this can damage the mouth and digestive tract of Arowanas. Always thaw frozen food before feeding – if frozen food is ingested the rapid drop in internal temperature will cause shock to fish.
HERMINATION FEEDING TECHNIQUE
Always feed fish before going you sleep – feed fish at night, not during the day.
Just like humans and most other living organisms fish function on cycles of sleep and activity. Arowana fish rest during the nighttime when its dark, they are active during the day when the lights are back on.
One of the most attractive traits about Arowana is they are extremely active fish, constantly thrusting their large bodies around the tank during the day. This requires a lot of energy and creates hunger. If you do not feed the Arowana to replenish their energy, they will enter survival mode, eagerly searching for food, this will also trigger their stress, sometimes causing them to aggressively fight with other fish to find food at night.
If Arowana are fed at night, they go to sleep satisfied, they wake up the next morning after sleeping peacefully.
Arowana have fatty tissue issues – their eyes will droop if there is too much fat.
