3. Red-tailed Arowana
Red-tailed Arowana is distributed in Sumatra Island, Indonesia. The red-tailed arowana has a beautiful golden scale frame from the ventral side up to the fourth row of scales. The fifth and sixth rows are not like the cross-backed arowana, high-backed arowana, high-backed arowana, and high-backed gem. The main reason why the Arowana lights up like that is that its pearl scales do not show. This is also the most fundamental difference between the red-tailed Arowana and other such Arowana species.
