The Silver Arowana (Osteoglossum bicirrhosum) is one of the most sought-after fish in the aquarist community. For many, it’s considered to be the pinnacle fish of the hobby. These freshwater fish are absolutely stunning, but they are not for the faint of heart! This is a very beautiful and a fascinating fish to watch. However, because of their huge adult size they are not recommended for the beginning aquarist. Actually, this is one of those fish that are probably best kept in the wild or in huge public aquariums.
