Despite legal limitations, captive breeding challenges, not to mention their high cost, the Asian varieties will probably often be the most desired 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 form 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 do not want the values Asian Arowanas command. What can you do if you’re one of the many without access to your preferred fish? Until it will become available, have a practical approach and revel in an intriguing, amazing alternative.
Introducing the Silver Arowana
Silver Arowanas are an outstanding alternative to Asian Arowanas that are nearly always available and affordable. They are often the initial species of Arowana aquarium enthusiasts are in contact with and offer an expense-effective introduction to the good care of Arowanas. When considered independently without comparison to Asian Arowanas, Silver Arowanas are quite impressive and captivating. During those times, with very little contact with the asian variety, nobody could have convinced me some other fish could be more intriguing!
Osteoglossum bicirrhosum was 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 as well as 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, inside the wild they consume fish, insects, spiders, birds, and even bats.
Physical Attributes of the Silver Arowana
Like Asian Arowanas, Silver Arowanas are true bony-tongues. They are primitive and prehistoric fish. In addition to their bony tongues, Silver Arowanas also hold the chin barbels sign of Asian Arowanas. They have a more elongated, tapered appearance than their Asian cousins, and their fins are significantly longer. The dorsal and anal fins of Silver Arowanas appear nearly linked to their caudal fins. The females tend to have a deeper body shape than males, and males have a more elongated jaw in comparison with females.
Silver Arowanas are incredibly large fish typically reaching 24 – 30 inches in captivity, though they can become adults to36 inches. Inside the wild, Silver Arowanas may grow as big as 4 feet long!
Those new to Silver Arowanas often consider their coloration to become “silver” without much variation. In reality, there is a lot of variation among these fish when it comes 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 more flat and dull in tone. They may be solid colored or possess or reflect flecks of blue, red, or green inside their opalescent scales. Most have a characteristic blue coloration behind the gills. The fins and tails of Silver Arowanas can be red or blue along the edges or in their entirety.
Silver Arowana Temperament
Silver Arowanas are predators with similar temperaments to Asian Arowanas. They may consume anything sufficiently small to suit in their mouths and they are best kept alone being a single species representative. Tank mates suitable for Asian Arowanas will likely do well with Silver Arowanas. They ought to be large, bottom dwellers or fast, mid-tank swimming fish that tend to avoid the Arowana’s way!
Many experienced hobbyists claim Silver Arowanas are slightly more skittish than Asian Arowanas. They have a good reputation for being quicker “tamed.” Silver Arowanas tend to be trained to take food right 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 want large tanks, immaculately clean, well-maintained water, and a varied, good quality diet. Careful awareness of their environment helps prevent zeinrk start of typical Arowana diseases. Droopy Eye is perhaps the most common affliction Silver Arowanas suffer.
One consideration relates to Silver Arowanas that is no longer a concern when acquiring an Asian Arowana. Whilst they are currently bred in captivity, a sizable majority of Silver Arowanas commercially available are still wild caught. Make sure to inquire about the origin of the fish you buy and take extra precautions with wild caught specimens. If they are thriving in captivity in the pet shop, mimic their water conditions and tank set-up as closely as possible.
Jumping is of course a problem with any Arowana, but particularly one which is wild caught. A very tight lid is completely necessary to prevent a Silver Arowana from harming itself, especially during the initial few weeks and months of captivity. Many hobbyists suggest lowering water amount of the tank somewhat during the first few weeks of acclimatization.
