Black Mary is an ovoviviparous fish that is sexually mature at the age of 5 to 6 months. It is advisable for black Mary fish to breed in groups, that is, to breed a variety of aquatic plants in a larger aquarium, apply strong light, put more than 10 pairs of fish, keep the water temperature between 26 and 28C, strengthen daily management, and find that there are larvae and fish out for another raising. If large pebbles are placed on the bottom of the aquarium, the newly born larvae may hide in the cracks of the rocks to prevent the mother from ingesting them.
Freshly laid larvae are dark black and turn gray after a few weeks, turning jet-black after chase.
Black Mary fish have a strong reproductive ability, and can reproduce every 4 6 weeks, giving birth to 10 to 50 larvae each time. Freshly after giving birth, females need to rest alone for about a week. It is more difficult to raise and breed some of the precious species of black maryfish.
The main thing is to ensure excellent living conditions and keep the water fresh, but not to add a large amount of new water frequently, add a small amount of salt when changing the water, and feed more palatable plant bait. Rare species have weaker fecundity and a smaller number of litters, generally between 10 and 30, and the time interval between hatchlings is also longer.

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.

At first glance, it turns out that the female Mary fish with a big belly has a small belly, and a small belly means that the small fish has been produced. In the water, you can see small fish the size of a grain of rice swimming in the water, so it can be said that the Mary fish has given birth to small fish. When the mother fish gives birth to small fish, separate the mother fish to prevent the mother from eating the small fish, it is better to raise the small fish separately, and feed the small fish after the feed is broken.
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.

Look at the belly: Mary fish are ovoviviparous fish, and when they are about to give birth, their belly will become very large. And their abdomen will also become darker in color and show signs of blackening.
Look at the reproductive holes: when the Maryfish are close to giving birth, their spawning tubes will fall, and some will have a dotted protrusion.
Look at the amount of activity: Mary fish that are close to birth will be less active due to their larger abdomen, and they will often hide alone in a corner or hidden place.
1. Small fish: The small fish just born of Mary fish are more sensitive to changes in the environment, and the keeper tries to keep them in the breeding tank and do not transfer them to other containers. The water temperature in the breeding tank should be kept at 25 and the water quality should be clean and refreshing.
Since small fish cannot adapt to environmental fluctuations, try not to change the water within a week of birth.
2. Broodstock: After the birth of Mary fish, the body will become weaker, and the keeper can transfer them to a separate container and feed them a lot of food to help them recover their strength.

3. Behavioral changes in females: Pregnant females tend to show unusual behavioral changes before giving birth, such as being more active, eating more or not eating, and preferring to hide in crevices or half-hidden.
4. Changes in the water quality of the fish tank: The water quality of the Mary fish must be kept in an ideal state before giving birth, not too turbid or the water temperature is too high or too low.

After the birth of the Mary Fish, the belly will return to the state before the pregnancy, and the keeper can judge whether the production is complete by observing whether the belly of the fish has recovered. It can also be judged by the number of litters. Generally, Mary fish produce 10-20 small fish at a time, and if the number of small fish they produce reaches this standard, it means that they have completed production.
However, there are also a large number of Mary fish breeding, which requires the breeder to make a comprehensive judgment from two aspects. <
Mary fish are ovoviviparous, and their abdomen will become very large when they give birth, and if they are finished, the belly will return to its pre-pregnancy state, so the keeper can tell if it has finished giving birth by the size of their abdomen. It can also be judged by the number of fish they produce, Mary fish can normally produce 10-20 small fish at a time, and the newly born small fish can move in the water, if the keeper can see the small fish swimming in the water, and the number is about 10-20, they may be finished. However, some Mary fish will have a higher number of litters, and the keeper needs to combine the size of their abdomen with the number of eggs laid to make an accurate judgment.
1. Broodstock: After the Mary fish is produced, the broodstock needs to be fished out immediately to prevent them from eating the small fish. But don't put the freshly given Mary fish back into the tank, or the male will chase them down.
2. Small fish larvae: Mary fish are ovoviviparous, so what is born is small fish larvae. The baby fish swim after birth, and the keeper needs to change the water first, because the Mary fish can pollute the water quality during the birth.
Then feed food, you can feed some cooked egg yolks, shrimp eggs and other foods.

The generator set is generally composed of a diesel engine and a generator and a control part, and the name is named after the diesel engine of the power part, so in general, the generator part will be unconsciously ignored, but the engine is also an important factor affecting the life and use of the generator set, just like a very high bucket missing a corner, then its height can only be below that corner. So we should also take into account the part of the engine when choosing, first of all, look at the manufacturer's popularity and reputation, and secondly, we can also check some qualification documents and authorizations, Komler Power is a lot of big-name generators (Cummins, Volvo.
