Despite legal limitations, captive breeding challenges, and of course their high cost, the Asian varieties will most likely always be probably the most sought after Arowanas. Perhaps nothing can compare with the splendor of Cross back Golden Arowanas. The brilliant coloration of Red Arowanas is equally hard to rival. No matter what kind of Asian Arowana one considers, hardly any other species rivals its status as King of the Aquarium.
Yet for many, the King remains off-limits because of their location and trade restrictions. Others simply cannot afford the prices Asian Arowanas command. What can you are doing if you’re among the many without use of your chosen fish? Until it becomes available, require a practical approach and enjoy an intriguing, amazing alternative.
Introducing the Silver Arowana
Silver Arowanas are a great option to Asian Arowanas which can be nearly always available and affordable. They are generally the first species of Arowana aquarium enthusiasts are subjected to and provide an expense-effective introduction to the proper care of Arowanas. When considered independently without comparison to Asian Arowanas, Silver Arowanas are quite impressive and captivating. At that time, with very little being exposed to the asian variety, nobody might have convinced me some other fish might be more intriguing!
Osteoglossum bicirrhosum was first given its species status in 1829 in France. Zoologist George Cuvier is mainly responsible for its recognition. Silver Arowana originate from South America where they naturally inhabit floodplains and freshwater parts of the Amazon River and its Basin. They inhabit mainly swamps and shallow waters of flooded areas, and their distribution indicates Silver Arowanas usually do not swim through rapids. As surface dwellers, inside the wild they consume fish, insects, spiders, birds, and even bats.
Physical Features of the Silver Arowana
Like Asian Arowanas, Silver Arowanas are true bony-tongues. They are primitive and prehistoric fish. Together with their bony tongues, Silver Arowanas also have the chin barbels manifestation of Asian Arowanas. There is a more elongated, tapered appearance than their Asian cousins, as well as their fins are significantly longer. The dorsal and anal fins of Silver Arowanas appear nearly connected with their caudal fins. The females tend to have a deeper figure than males, and males possess a more elongated jaw in comparison to females.
Silver Arowanas are extremely large fish typically reaching 24 – 30 inches in captivity, although they can grow up to36 inches. Inside the wild, Silver Arowanas may grow as huge as 4 feet long!
Those unfamiliar with Silver Arowanas often consider their coloration to become “silver” without much variation. In reality, there exists significant amounts of variation among these fish with regards to their brilliance and coloration. The coloration of Silver Arowanas is so pronounced, many hobbyists boost their color through special diets just as Asian Arowana enthusiasts do!
Silver Arowanas may use a silvery, light grey, or strikingly white body coloration. It may appear highly metallic having a high sheen, or even more flat and dull in tone. They may be solid in color or possess and reflect flecks of blue, red, or green within their opalescent scales. Most use a characteristic blue coloration behind the gills. The fins and tails of Silver Arowanas can be red or blue along the edges or perhaps in their entirety.
Silver Arowana Temperament
Silver Arowanas are predators with similar temperaments to Asian Arowanas. They may consume anything sufficiently small to match inside their mouths and they are best kept alone as being a single species representative. Tank mates suitable for Asian Arowanas will probably do well with Silver Arowanas. They must be large, bottom dwellers or fast, mid-tank swimming fish that have a tendency to avoid the Arowana’s way!
Many experienced hobbyists claim Silver Arowanas are a little more skittish than Asian Arowanas. They have a reputation for being quicker “tamed.” Silver Arowanas tend to be educated to take food straight from fingers, while Asian Arowanas are rarely so docile!
Good care of the Silver Arowana
Silver and Asian Arowanas require nearly identical habitats and care. They need very large tanks, immaculately clean, well-maintained water, and a varied, high quality diet. Careful awareness of their environment aids in preventing zeinrk onset of typical Arowana diseases. Droopy Eye could very well be the most common affliction Silver Arowanas suffer.
One consideration applies to Silver Arowanas that is no longer an issue when acquiring an Asian Arowana. When they are bred in captivity, a large most of Silver Arowanas commercially available continue to be wild caught. Be sure to find out about the origin from the fish you buy and take extra precautions with wild caught specimens. Should they be thriving in captivity at the pet shop, mimic their water conditions and tank set-up as closely as possible.
Jumping is needless to say a problem with any Arowana, but particularly one which is wild caught. A really tight lid is completely required to prevent a Silver Arowana from harming itself, especially during the first weeks and months of captivity. Many hobbyists suggest lowering water amount of the tank somewhat during the first weeks of acclimatization.
