First of all i just want to say all of you guys HELLO and have a nice day.
Today, i just want to share to you about AROWANA and what kind of fish is this.

So what is arowana?
According to Wikipedia and based on my research, arowana are freshwater bony fish of the family osteoglossidae, it's also know as bonytongues (the latter name is now often reserved arapaimidae). In this family of fish, the head of bony and the elongated body is covered by large, heavy scales, with a mosaic pattern of canals. The dorsal and anal fins have soft rays and are long based. While the pectoral and ventral fins are small. The name bonytongues is devired from a toothed bone on the floor on the mouth, the tongue, equipped with teeth that bite against teeth on the roof of the mouth. The arowana is a facultative air breather and can obtain oxygen from air by sucking it into its swim bladder, which is lined with capillaries like lung tissue.

Sometimes referred to as the dragon fish. Arowanas are one of the most beautiful and most fascinating species of fish in the aquarium trade. They are considered a jurassic era species and have been around for over a 100 million years. The arowana is the has a bony head and a long powerful body.
