There are two ways to distinguish this fish:
One is to look at the dorsal fin, which is very close to the tail, and some of them are almost next to the tail. It is a male fish, and vice versa.
The second is to look at the belly, the belly of the female fish is generally larger than that of the male fish. Because there are eggs in the belly of the adult fish.

Although the characteristics of male and female are not obvious before the seedlings mature in stages, the sex is not easy to distinguish. However, when the blue man arowana reaches sexual maturity, the performance becomes obvious, and there are the following characteristics:
In the female Blue Mansaurus, the abdomen of the female develops into a plump shape, providing space for the growth of the seedlings that will be propagated later. The dorsal fin is rounded, the body color will be dull compared to the body, and the base of the thorax is not particularly thin orange-red.
In the male, the abdomen of the male is not as full as that of the female, but the dorsal fin is long and pointed, and the body color is bright, and the pectoral fin is basically orange-red and relatively bright.
The male and female of the blue man arowana can distinguish the success of reproduction faster, put the blue man arowana into the aquatic plant box with large leaves, and at the same time bury the ceramic cup in the bottom sand, the water temperature is controlled between 29-31 °, and the water should not be changed within 3 days. For the first two days, turn on the fish tank lights 24 hours a day and feed a small amount. On the third day, the water temperature is constant at 30 °, basically begin to chase the big reproduction fertilization, the fourth day will see the spawning, after 4 hours to turn yellow for the red blood filament, then you can take the chaos from the aquatic plants China, put it into the prepared ceramic cup, almost 15 hours later, it will turn black and purple, and basically hatch the next day.

Blue Man Arowana. Blue Manlong.
Scientific name: trichogaster trichopterus
Origin: Thailand, Malaysia, Indonesia, etc., belonging to the betta family. The body length is 10-12 cm, oval. Azure.
The water temperature is 22-27 degrees Celsius, and the water quality requirements are self-evident. The bait includes fish insects, water earthworms, etc. The breeding water temperature is 26-27 degrees Celsius.
The males have bright body colors, with long pointed dorsal fins at the end, and females have a light body color. It is a foamy oviparous fish. Females lay 500-1000 eggs each time, with an interval of 10-12 days.
The age of sexual maturity of broodstock is 6 months. It has a mild temperament and can be polycultured with other fish. When there is a lack of oxygen in the water, it can be breathed directly out of the water.

Before the blue mansaurus reaches sexual maturity, the male and female characteristics are not obvious, and the sex is difficult to distinguish, so you can compare it by careful observation
Body color: males are brighter in color, while females are darker;
Dorsal and pelvic fins: males have large dorsal fins with pointed dorsal and anal fins, while females have smaller dorsal fins and rounded and blunt dorsal and anal fins.
Abdomen: Males have less than full abdomen, while females have fuller abdomen;
Filiform pectoral fins: The base of the filiform pectoral fins of males is distinctly orange-red, while the base of the filamentous pectoral fins of females is not distinctly orange-red.
When frightened, both male and female fish show irregular slanted stripes on their bodies.

Hello, there are the following key points for male and female Arowana: 1. Judging from the dorsal fin, the end of the dorsal fin of the male fish is pointed and long, and the dorsal fin of the female is short and rounded; 2. Judging from the body size, the male fish is slender and long, and the female fish is short and rounded, 3. Judging from the belly, the male fish has a smaller belly because of its slender body size, while the female has a larger belly because of reproduction.
The first (most simple and clear) star-chasing male's first fin has milky white star-chasing females have none Second, body type The males are thin and long, the females have a short and thick body, and the hind abdomen is large, and the breeding period is more obvious The third cloaca The males are small and long, with pointed ends and concave inwards, and the females are large and round, pear-shaped, and slightly convex outwards.
It should be hermaphroditism, because I caught one and kept it in the fish tank, and after a while it lay eggs, and after a while, it lay eggs, and it has been spawned three times, and it can hatch, the first time I had no experience and thought it was an egg, and I fed the fish directly, and the second time, I knew that it was the egg of the Fushou snail, so I deliberately put it, and then it hatched out, but it was all eaten by the fish, and this time I put it in another fish tank.

1. Water temperature. The water temperature of the black feather fish should be between 23 and 28, and the growth temperature should be 25. The suitable water temperature for juveniles should be between 26-28, and the width of the hole should not exceed 4 during the day and night, otherwise it will affect the survival and growth of juveniles. The water temperature should be kept constant during reproduction, which is more conducive to broodstock production, egg hatching and juvenile growth. >>>More
