Common name: Black Arowana.
Species name: Osteoglossum ferreirai.
Maximum size: 95cm
Origin: Amazon Basin in French Guiana, Brazil and Peru,
pH Range: 5.5 - 7.0
Temperature: 24 - 30°C
Company: As juveniles its best if 6 to 10 are kept together, the same rule applies with adults, but be careful as some adult Arowana do not tolerate others of their own kind well. Besides keeping them in schools they can be kept with peaceful to moderately aggressive fish that are big enough not to be eaten and that will also most importantly not harass or harm your Arowana.
Aquarium setup: Black Arowana should be kept in a very large Aquarium or a garden pond. They do grow to be large fish and so they will require large volumes of water. Be aware they can suffer from stunted growth and can die of organ failure if they are kept in undersized Aquariums. It is also critical that the aquarium has a tight fitting and secure lid that is extremely strong. Their tank should be placed in a low traffic area to keep the Arowana from getting frightened by sudden movements. Lighting should preferably be dimmed instead of suddenly turned on or off to prevent shock. All Arowana prefer very clean filtered water and they do not tolerate poor water quality, so excellent filtration along with frequent partial water changes of 25% or more is required to keep nitrate levels low.
Note: They do enjoy a sand substrate and driftwood branches to replicate their natural habitat although this is not essential.
Breeding: Arowana are mouth brooders and are easily bred in large ponds, but difficult to breed in aquariums. The male keeps the eggs in his mouth for a month before the eggs hatch out. The fry then remain in the mouth for another two to three months.
The Black Arowana are naturally found in the freshwater reservoirs of the Amazon Basin in French Guiana, Brazil and Peru. The Black Arowana has scales and fins that are black with whitish to yellow strips when young. But as it matures, it will slowly lose its colour and turn to more greyish colour. These Arowana are known to inhabit blackwater rivers, slow-moving waters flowing through forested swamps and wetlands, where adults feed on other fish, while juveniles feed on insects.
Arowana are often called “Dragon Fish” because of their enormous scales and long, chin barbels. When they glide gracefully through the water, their pectoral fins often spread out, resembling a dragon in full flight.
Black Arowana Diet.
As with all Arowana species the Silver Arowana can be very choosy towards its food. They will go without food for weeks if their favorite food is not given.
There are several different things that you can try in small quantities. fish, shrimp, chicken breast and other easily available meats are great options. Live feed like small fish, rodents, small amphibians, mealworms and insects are also good options. There are commercial pellets available on the market which you can use for the staple diet but you may need to introduce these slowly until the Arowana realises that they are a food source and does not refuse them.
