Compatibility

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 all bottom dwellers are tolerated. Other aggressive fish may ruin the long flowing fins of a beautiful Arowana.

Habitat Maintanence

Check filter, other equipment and water temperature daily
Check water quality at least once a week
Change 25–50% of the total volume of water every week, or as needed

Characteristics of Arowana

Posted on 2:12 AM No Comments

Arowana have Mandibular Barbels or Whiskers that are used to sense movement on the
water surface.

Decorate with minimum plants and décor to allow maximum swimming area and yet provide a
hiding place. Avoid sharp objects upon which an Arowana could injure itself.

How To Care For An Arowana

Posted on 9:10 PM comments (1)

Average
Size Up to 24 inches long, in captivity

Life Span
Up to 10 years with proper care

Diet

Arowana is carnivorous. In the wild its food consists mainly of insects, fishes and worms Provide live or frozen fish and insects, krill, worms and shrimp (for young Arowana avoid
insects or inverts with sharp or very hard shells) Thaw frozen foods before feeding Provide pellets designed for surface feeding carnivorous fish (or Arowana pellet food)

Feeding
These fish are surface feeders often gliding just below the water surface. Feed young fish 2-3
times a day and adults once a day, feed only what they can eat within 3-5 minutes. Feed carefully as Arowanas usually attack their food coiling their bodies like a spring and lunging forward to engulf the food

Housing
The Arowana is a surface swimming fish, width (front to back) of the tank is more important
than its height (top to bottom). A general rule is the width of the tank should be at least the
length of the fish. For an Arowana baby a 20 gallon long is adequate for the first two or three
months. (Beware that if a fish is left in too small of tank a permanent spinal curvature can
occur.) As the fish grows a 55 gallon, then a 125 gallon, and finally a 180 gallon plus for a fullgrown fish is recommended. Always keep tank covered as this fish is an active jumper
Provide proper filtration to maintain health, and perform 25-50% water changes weekly.
Arowana are more sensitive to nitrites than other fish. Water temperature should range from 72° F. to 82° F.

Arowana Species

Posted on 5:00 AM No Comments

Arowanas, also known as aruanas or arawanas are freshwater bony fish of the family Osteoglossidae, sometimes known as "bony tongues." In this family of fishes, the head is bony and the elongate body is covered by large, heavy scales, with a mosaic pattern of canals. The dorsal and the anal fins have soft rays and are long based, while the pectoral and ventral fins are small. The name 'bony tongues' is derived from a toothed bone on the floor of the mouth, the 'tongue', equipped with teeth that bite against teeth on the roof of the mouth. The fish can obtain oxygen from air by sucking it into the swim bladder, which is lined with capillaries like lung tissue
