Despite legal limitations, captive breeding challenges, not to mention their high cost, the Asian varieties will probably often be probably the most popular Arowanas. Perhaps nothing can compare with the splendor of Cross back Golden Arowanas. The brilliant coloration of Red Arowanas is equally hard to rival. Regardless of what form of Asian Arowana one considers, no other species rivals its status as King of the Aquarium.

What can you are doing if you’re among the many without use of your favorite fish? Until it will become available, require a practical approach and revel in an intriguing, amazing alternative.
Introducing the Silver Arowana
Silver Arowanas are an excellent option to Asian Arowanas which are nearly always available and affordable. They are generally the first species of Arowana aquarium enthusiasts are exposed to and provide an expense-effective guide to the proper care of Arowanas. When considered independently without comparison to Asian Arowanas, Silver Arowanas are very impressive and captivating. During that time, with very little exposure to the asian variety, nobody might have convinced me some other fish may be more intriguing!
Osteoglossum bicirrhosum was given its species status in 1829 in France. Zoologist George Cuvier is 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 do not swim through rapids. As surface dwellers, in 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. Along with their bony tongues, Silver Arowanas also have the chin barbels sign of Asian Arowanas. These people have 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 associated with their caudal fins. The females usually have a deeper figure than males, and males use a more elongated jaw in comparison to females.
Silver Arowanas are incredibly large fish typically reaching 24 – 30 inches in captivity, even though they can become adults to36 inches. In the wild, Silver Arowanas may grow as large as 4 feet long!
Those not familiar with Silver Arowanas often consider their coloration to get “silver” with little variation. In fact, there is certainly 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 have a silvery, light grey, or strikingly white body coloration. It may appear highly metallic using a high sheen, or even more flat and dull in tone. They may be solid in color or possess and/or reflect flecks of blue, red, or green within their opalescent scales. Most have a characteristic blue coloration behind the gills. The fins and tails of Silver Arowanas can be red or blue across the edges or in their entirety.
Silver Arowana Temperament
Silver Arowanas are predators with a similar temperaments to Asian Arowanas. They may consume anything small enough to match within 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 slightly more skittish than Asian Arowanas. They also have a track record of being easier “tamed.” Silver Arowanas are frequently 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 require very large tanks, immaculately clean, well-maintained water, as well as a varied, top quality diet. Careful awareness of their environment helps prevent zeinrk beginning of typical Arowana diseases. Droopy Eye is perhaps the most typical affliction Silver Arowanas suffer.
One consideration applies to Silver Arowanas that is not a problem when acquiring an Asian Arowana. Whilst they are bred in captivity, a big most of Silver Arowanas commercially available remain wild caught. Be sure to ask about the origin in the fish you purchase and take extra precautions with wild caught specimens. If they are thriving in captivity on the pet shop, mimic their water conditions and tank set-up as closely as is possible.
Jumping is of course an issue with any Arowana, but particularly one that is wild caught. An extremely tight lid is absolutely essential to prevent a Silver Arowana from harming itself, especially during the first few weeks and months of captivity. Many hobbyists suggest lowering this type of water level of the tank somewhat during the first few weeks of acclimatization.
