Arowana fish is for those who want to add elegance to their aquarium. They are sometimes referred to as “dragon fish” or “Arowana dragon fish“. The rather peculiar shape of their mouth, which stretches upwards, is what sets them apart. They have a bony head and a rather elongated body. Fins vary from small to large sizes. Some people are used to calling them “bony tongues” for the thongs they have at the edge of their mouth.
Arowana fish have different subclasses; silver arowana fish, red arowana fish, African arowana fish, Asian or golden arowana fish, northern arowana fish and black arowana are commonly known subclasses. These subclasses are defined on basis of their shape, style of fins, size and origin and habitat etc.
The most common variety of the well known Asian arowana fish, the green arowana fish is native to the waters in Indonesia, Thailand and Malaysia. This particular variety is the cheapest breed compared to other popular varieties of the Asian arowana. (Bukit Merah blue, Red-tailed Golden and Gold Cross-back are some of the expensive varieties you can buy)
