Mary Ball Fish is born two and then it is not born What is the situation

Mary conglomerates once a month and hatches within 24 hours. During the breeding season, care should be taken to provide a comfortable and quiet production environment for the mariculus and prepare sufficient food. After the Mary ball fish is produced, pay attention to the isolation of the juveniles and females.

Mary ball fish reproduce once a month, and the eggs are generally hatched within 24 hours. At the age of nine to ten months, the Mary coness are sexually mature and ready to reproduce.

During the breeding period, care should be taken to provide a quiet and comfortable production environment for the Mary Ball Fish, and feed the Mary Ball Fish after giving birth so that the fish can recover their strength. In addition, care should be taken to keep Marie ballfish and juveniles separately.

Newly hatched Marie ball fish juveniles do not need to be fed and need to wait until the third day to feed. Juvenile Mary ball fish can be fed egg yolk and juvenile feed, feeding other foods will increase the gastrointestinal burden of juveniles.

A large fright in the broodstock or a sudden change in water quality can cause ovoviviviparous fish like Mary to give birth prematurely, resulting in eggs instead of small fish.

Ovoviviparous, easy to reproduce, male dorsal fin is high and wide, anal fin is pointed: female individual is larger, anal fin is round, breeding water temperature is about 26 force, male to female ratio is 1:2.

Put the densely planted aquatic plants into the breeding box, wait for the female's abdomen to swell, and remove the males, each female gives birth to 30 50 litters each time. Once the larvae are produced, they can swim and feed. The same method of raising and reproducing is also the silver Mary fish, the multicolored Mary fish and the ball silver Mary fish.

It is necessary to use a strip-shaped Mary male to match, so that there can be more fish larvae.

Look at the abdomen: When the black Mary is about to give birth, the abdomen will become very large, and close to the time of delivery, their belly may exceed the size of the body.

Look at the cloacal pores: 2-5 days before the black Mary ball fish is born, the cloacal pores will turn white.

Look at the activity: When the black Mary ball fish is about to give birth, it likes to hide alone in the corner. Due to the large abdomen, they may also experience decreased activity and abnormal swimming.

Black Mary fish belong to ovoviviparous fish, so they are not produced in large quantities at one time. Normally, they can produce 40-100 small fish at a time. However, there are also some black Mary fish with strong reproductive ability or large size, which can produce 200 small fish at a time.

Although they produce a large number of small fish, the chances of survival of small fish are not very high, so the overall reproduction volume is not very high. In order to improve their survival rate, they need to control the temperature and quality of water after birth, so that they can quickly adapt to the external environment.

<> Mary ball fish is about to be raw, in addition to the belly will swell, the appetite will also decrease. The length of this fish is about 4-5 cm, its belly bulges like a leather ball, and by the breeding season, the males will become bright in color and the females will have a light body color. This fish has a very mild temperament and can be polycultured with small tropical fish, the temperature is generally between 25-28, and the water quality is generally hard water.
