Silver Arowana by LiveAquaria
The Silver Arowana, also known as Arahuana, is a true bony fish scientifically classified as Osteoglossum bicirrhosum. It is sometimes referred to as O. vandelli or Ischnosoma bicirrhosum. Native to the flood plains of the Amazon River Basin in South America, this species is part of the band fish group.
It can grow up to 47 inches in the wild and is best suited for advanced freshwater aquarists due to its size and care requirements. The Silver Arowana can survive short periods out of water by breathing air through its swim bladder.
It thrives in a 250-gallon tank with a fine gravel substrate, loosely planted vegetation, and soft, peaty water conditions. Open swimming space is essential for its well-being.

I’ve had my Silver Arowana for six months now. It’s a striking fish with a beautiful silver sheen. The tank setup took some time, but once I got the water chemistry right, it’s been very active and healthy. I’m an experienced aquarist, and this species is definitely not for beginners.

The fish arrived in good condition and has been adjusting well. I followed the setup guide carefully, including the soft water and fine gravel. It swims freely and seems content in the open space. A bit of a challenge to maintain, but worth it for the visual impact.
