Arowana is highly sought after by ornamental fish lovers for its bright colors and peculiar shape. However, I believe that many novice aquarists are often confused by the many varieties of arowana. Today, I'm going to give you a detailed look at how to accurately identify Arowana so you can breed, communicate, trade and even make aquarists!
1. Identify by the species of Arowana
The species of Arowana are different, and the appearance is naturally very different. At present, the common species on the market include Thai Arowana, Malaysian Arowana, Indonesian Arowana and other categories. Among them, Thai arowana is divided into golden dragon, red dragon, silver dragon, copper dragon, black dragon, etc., Malaysian arowana mainly includes red dragon flower, yellow-headed red dragon, gold-headed red dragon, etc., Indonesian arowana is dominated by money dragon. By learning the laws of Arowana species, you can easily distinguish different species.
2. Identify by the shape of the Arowana
The most distinctive feature of the Arowana is the "mane fins" on the head and sides of the body, which is the origin of the name of the Arowana. In addition, the pectoral fin, dorsal fin and caudal fin of the dragonfish also have obvious characteristics, such as a white margin on the dorsal fin of the golden dragon, the geometric scale of the black dragon, and the curved surface of the scale of the red dragon. By carefully observing the appearance characteristics of Arowana, it is not difficult to distinguish the various species clearly.
3. Identify the sex of the Arowana through its mating
It is not easy to distinguish between male and female sexes of Arowana, especially when Arowana is less than 6 months old. However, Arowana has very obvious characteristics when mating. During egg holding, the abdomen of the female Arowana will be visibly inflated when it is about to lay eggs, and the owner can generally be clearly observed with the naked eye. However, it is important to distinguish between an arowana caused by abdominal bulging caused by eating too much or egg holding. In general, if the abdomen of an arowana is swollen due to eating, the scales of its abdomen will be staggered, and the white part of the edge of the scales can also be seen. If the female also has a bulging belly without feeding, and this condition has existed for a long time, it can be considered that the Arowana is holding the eggs. After the eggs are fertilized, the male will contain all the eggs in the mouth, if the number of eggs is large, the male fish does not contain so much, the female will swallow part of the eggs, preventing other fish from gathering to swallow the eggs, which is also the reason why the Arowana hatches fewer juveniles.
Through the previous introduction, I believe that everyone has mastered how to distinguish the dragon fish, and can better recognize and raise these cute pets. Of course, the details need to be studied and studied. If you want to know more about Arowana, you can communicate with other aquarists, participate in various fish shows and exhibitions, and improve your breeding skills.
