Silver Arowana/Osteoglossum bicirrhosum
They can grow to around 48 inches in the wild, and are usually the cheapest Arowana species. Silver Arowana can be more jumpy then the other species and more than one Silver Arowana have jumped to their death in a badly covered aquarium.
Silver Arowana may take a while to adjust to non-live food. Sometimes to the brink of starvation. Feed them meaty food like, fish, crab, or Shrimp (try to avoid the salt). This Arowana Fish thrives in temperatures between 75 and 86 degrees Fahrenheit (24-30 C), and pH between 6 and 7. Young Silver Arowana should not be in a tank shorter then 36 inches/ 90 cm, and as they get older, 48 inches/ 120 cm though when your Arowana fish reaches 15 inches/ 40 cm they will need a much larger tank. These Arowana Fish can become aggressive towards similar species and should be kept alone in the aquarium tank unless it is very big. They can also be kept with larger catfish and a few other species. They are a definitely predator and will eat smaller fish. As juveniles, they may be suitable for smaller home aquarium, though with growth, they are likely to outgrow the home and become suitable only for large public aquariums.
One of the most interesting fish, the Silver Arowana gets rather large. A 47 inch specimen, although rare, will need an aquarium of at least 100 gallons just to turn around! Though they can be kept together when small, larger specimens are best kept singly or with other species of larger fish. They are a predator and will eat small fish. But on a positive note, they can become quite tame and take food from your fingers.
To breed feed large amounts of live food to induce spawning. The eggs are up to 1/2 inch in diameter. The male will brood them in his mouth. After 50-60 days the eggs will develop and produce fry which have and obvious eggsak. They are 3-4 inches long before this is gone and they will feed entirely on their own.
These fish are excellent jumpers so make sure the top of the aquarium is covered. The Arowana will prefer an aquarium with a fine gravel bottom planted loosely with hardy plants and open areas on the top to swim.
