Osteoglossum bicirrhosum (Silver Arowana, Dragon Fish)

The Silver Arowana is a much sought after fish, normally the crowning jewel in any collection. They are large and silver coloured, and can grow up to 4 foot (120cm) in the wild, however when kept in captivity you should expect them to grow to around 3 foot (around 90cm). The average Arowana will weigh around 4.6kg (10lb) when fully matured.

Its most distinguishing characteristic is its jawline. Affectionately referred to as a ‘drawbridge’, their mouth is nearly vertical. As for their body, they have large pearl-like silvery scales running across their entire body. It's worth noting, amongst juveniles these scales may have a blueish tint to them.

This big, elongate fish with large shiny scales and a distinctive up-turned mouth also possess a pair of leaf-like "feelers" at the tip of the lower jaw. The dorsal, anal, and tail fins form a single long fringe.

Originating from South America and renowned for their hunting ability and large size, this fish is one of the most iconic around and will be the prized possession of any hobby aquarist. Whilst not generally recommended for beginners, this fish can make a fantastic addition to an experienced keeper’s tank.

Fish information (behaviour and breeding):

An outstanding fish for the aquarist with a gigantic aquarium, young species are often offered for sale at relatively low prices. Given their large adult size, as well as relatively rapid growth, they are not really suitable for most home aquaria.

In terms of temperament, these fish are not especially demanding. They get along well with other fishes of similar size such Green Terrors, Oscars, Knifefish, Large Plecostomus, Parrot Cichlid, Angelfish and Catfish. Although please remember that temperaments of individual fish can vary hugely, so it is best to always have a backup plan if they do not ‘get along’.

Breeding not achieved in domestic aquaria, but in public aquaria it has been observed. These fish are mouthbrooders, with the males protecting the eggs and fry.
