Arowana, also known as red-tailed arowana, is essentially different from arowana. Its main feature is that pearl scales do not emit light, and the scales can only emit light to the fourth row, and the fifth row and above are basically not displayed, which is also determined by the pedigree of Arowana.

The performance of high-backed arowana is better than that of gemstone arowana. Their bead scales will not shine, but the fifth row of high-backed arowana will shine, unlike the fifth row of gemstone arowana, which is completely unlit.

Which variety is better depends mainly on your own preferences. There is a difference in price between the two, but it won't be very different.

Gem arowana is a carnivorous fish, which can feed small fish, shrimp, loach and other foods, but it can't feed animal viscera, which is easy to cause some arowana diseases and damage the digestive system of arowana. The adaptive water temperature of arowana, which belongs to the gemstone arowana pedigree, is between 24-29℃, but the drastic change of water temperature must be avoided, because arowana is very sensitive, and the drastic change of water temperature is likely to cause harm to it. The pH value of water body should be controlled between 7-8 and kept stable, providing a good living environment for jewel-like arowana.
