Arrowanas are freshwater bony fish of the family Osteoglossidae, also known as bonytongues.

In this family of fish, the head is bony and the elongated body is covered by large, heavy scales, with a mosaic pattern of canals. The arowana is a facultative air breather and can obtain oxygen from air by sucking it into the swim bladder, which is lined with capillaries like lung tissue.

There are ten described living species: three from South America, one from Africa, four from Asia, and the remaining two from Australia.

Arowanas are solitary fish and only appreciate company while young; adults may show dominance and aggression. Some compatible species often partnered with this fish are clown knifefish, pacu, oscars, plecostomus, jaguar cichlids, green terrors, gar, tinfoil barb, siamese tigerfish, and any other semi-aggressive fish that cannot fit in the arowana's mouth.

These fishes are best kept with live or frozen feed and they easily outgrow the tank within a span of 8 to 10 months. A large type aquarium of at least 150 gallons is preferable.
