How to distinguish male and female arowana

Speaking of arowana, I believe many fish lovers like it very much, because it not only has a sturdy body, short body and high back, beautiful patterns, but also very rich colors. What's more special is that the patterns are all different. Also, there is a bag on its head, which looks like the God of Longevity in mythology, so everyone regards it as a fish that represents health and longevity. However, because Arowana has a strong sense of self-territoriality, it is not suitable for mixed breeding, so today we will talk about how to distinguish male and female Arowana.

1. Male and female arowana

Regarding the question of how to distinguish male and female arowana, the following five points are generally used to distinguish:

1. Dorsal fin with spinous rays: If the first to sixth dorsal fin with spinous rays are thick and round, it is a male; if they are thin and flat, it is a female.

2. Pelvic fins: Touch the pelvic fins with your hand. The harder ones are those of males, and the softer ones are those of females. This is because females must use their pelvic fins to shake during reproduction to provide oxygen to the eggs, prevent bacterial invasion, and can also be used to sweep away debris.

3. Fish with pointed breasts are mostly females, while fish with round breasts are mostly males.

4. Body shape: Males usually have thicker bodies.

5. Genital pore: The genital pore is V-shaped in males and U-shaped in females.

Below, we will share with you how to distinguish male and female arowana fry and adult fish:

Flower Lohan is a hybrid fish species, and the method of distinguishing the black spots on the dorsal fin is not accurate. However, the general method of distinguishing the gender of a baby arhat cannot be used on the baby arhat, so the method of distinguishing the original kinship is used to increase the probability of distinguishing the gender of the baby arhat. Dorsal fin without black spot: 80% are males;

Dorsal fin has black spot: 60% are female.

Generally, young male arhats are braver, while young female arhats are easily frightened and turn black. If they are underfed and do not dodge when you wave your hand gently, they are mostly males, while those that continue to hide at the bottom of their feet and turn black are usually females. When they are full, if people approach, the female Arhats will usually run around, while the male Arhats will shrink into a corner. Observe the small fish of the flower lotus. If the abdomen is slightly bulging, it is more likely to be a female. If you turn over and look at the genitals, if there is something visible, it is a male, and if there is nothing visible, it is a female.
