Despite legal limitations, captive breeding challenges, not to mention their high cost, the Asian varieties will most likely always be 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. Regardless of 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 the geographical location and trade restrictions. Others simply cannot afford the costs Asian Arowanas command. What can one does if you’re among the many without access to your chosen fish? Until it becomes available, require a practical approach and appreciate an intriguing, amazing alternative.
Introducing the Silver Arowana
Silver Arowanas are an outstanding option to Asian Arowanas that are nearly always available and affordable. They are generally the initial species of Arowana aquarium enthusiasts are subjected to and supply a cost-effective overview of the good care of Arowanas. When considered independently without comparison to Asian Arowanas, Silver Arowanas are quite impressive and captivating. During those times, with not a whole lot contact with the asian variety, nobody might have convinced me any other fish may be more intriguing!
Osteoglossum bicirrhosum was initially given its species status in 1829 in France. Zoologist George Cuvier accounts for its recognition. Silver Arowana originate from South America where they naturally inhabit floodplains and freshwater parts of the Amazon River as well as its Basin. They inhabit mainly swamps and shallow waters of flooded areas, along with their distribution indicates Silver Arowanas usually do not swim through rapids. As surface dwellers, within 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 characteristic 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 generally have a deeper figure than males, and males possess a more elongated jaw in comparison to females.
Silver Arowanas are incredibly large fish typically reaching 24 – 30 inches in captivity, though they can become adults to36 inches. Within the wild, Silver Arowanas may grow as large as 4 feet long!
Those new to Silver Arowanas often consider their coloration to become “silver” without much variation. Actually, 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 have a silvery, light grey, or strikingly white body coloration. It may appear highly metallic having a high sheen, or maybe 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 sufficiently small to match in their mouths and they are best kept alone as a single species representative. Tank mates ideal for Asian Arowanas will likely do well with Silver Arowanas. They should be large, bottom dwellers or fast, mid-tank swimming fish that often avoid the Arowana’s way!
Many experienced hobbyists claim Silver Arowanas are a little more skittish than Asian Arowanas. They also have a good reputation for being easier “tamed.” Silver Arowanas tend to be taught to take food directly from fingers, while Asian Arowanas are rarely so docile!
Care of the Silver Arowana
Silver and Asian Arowanas require nearly identical habitats and care. They want huge tanks, immaculately clean, well-maintained water, and a varied, high quality diet. Careful focus on their environment helps prevent zeinrk onset of typical Arowana diseases. Droopy Eye could very well be 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 currently bred in captivity, a big greater part of Silver Arowanas commercially available remain wild caught. Make sure you ask about the foundation in the fish you get and take extra precautions with wild caught specimens. Should they be thriving in captivity in the pet shop, mimic their water conditions and tank set-as closely as is possible.
Jumping is of course an issue with any Arowana, but particularly one that is wild caught. A very tight lid is completely necessary 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 weeks of acclimatization.
