The selected broodstock are carefully raised in a large aquarium densely planted with aquatic plants, and the male is fished out after the female's abdomen is swollen to prevent the female from miscarriage and the larvae from being swallowed by the male. Each female can give birth to 30 50 hatchlings each time, juveniles can swim and feed after birth, the color of the newborn larvae is dark gray, and then gradually turn black, two months later can distinguish male and female, 5 months to reach sexual maturity. The breeding cycle is about 35 days.

Put the densely planted aquatic plants in the human breeding box, wait for the female's abdomen to swell, and take out the males, and each female will give 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.

All I know is Yellow Mary, Green Mary, Golden Mary, Samali, Garbage Mary, and I haven't heard of any Black Mary.

Black Mary Fish. The reproductive cycle is about one month. It takes about 20 days for them to give birth to small fish each time.

There is no need to feed on the first day of life, and from the second day, you can feed some egg yolk water or crumbs of shrimp eggs.

The breeding cycle of black maryfish is about one month. It takes about 20 days for them to give birth to small fish each time. After giving birth to the calves, the mother fish needs to be isolated and kept alone.

The duration of monoculture is about a week. This protects the mother and helps her recover from her postpartum weakness sooner. After recuperation, they can reproduce as broodstock again.

There is no need to feed the fish on the first day of life. The day after birth, it can be fed. Don't feed too much at this time, as they can also absorb nutrients from the yolk.

After another 1-2 days, it is ready to be fed normally. The frequency of feeding should be controlled, at first it can be fed once a day, and after it has absorbed the nutrients of lead in the yolk, it can be fed 2-3 times a day, and the amount of food can also be slightly increased.

When feeding Black Mary small fish, you should be sensitive to using foods with high nutritional value, easy to digest, and small particles. This kind of food is better for their growth. Specifically, you can feed it with egg yolk water made from boiled egg yolks, or you can feed it with the crumbs of shrimp eggs from the harvest years.

In addition, it can also be fed with crumbs from artificial fish feed.

<> Black Mary needs to keep it separately from the small fish after giving birth to the small fish, otherwise the small big hole fish is likely to be eaten by the larger fish. At the same time, it is best to take some of the water in the fish tank when the small fish were born and raise it in the new fish tank, so that the small cherry fish will not be unsuitable for the water quality.

When the baby fish is just born, there will be something like an egg yolk in the stomach, so don't feed it, otherwise the belly will burst even if it survives.

After 3 days, feed some cooked egg yolks. Pay attention to the water quality, change it immediately if it is turbid, and change it for about one-third to one-half at a time.

Black Mary is also known as Black Morley Family. （blackmolly/mollienesialatipinna）。It is a freshwater ornamental fish of the order Cypriniforma, a suborder of cyprinidonts, a family of flowers, and a species of freshwater ornamental fish that has been artificially bred.

Black Mary fish does not have strict requirements for water quality, prefers water containing trace amounts of salt, and the suitable water temperature is 20 24. If the temperature is low for a long time, it is easy to get sick.

For example, when the water temperature is below 18, it is susceptible to water mold. It has miscellaneous food habits and can scrape the algae and aquatic plants on the wall of the tank, so it has the reputation of "cleaner" of the aquarium. It has a mild temperament and is easy to mix.

Because black Mary fish prefer weakly alkaline hard water, it is not suitable for polyculture with tropical fish of the aliphaid family. Juveniles can be fed live bait such as small fleas. It is sexually mature in 5 months, and the reproductive cycle is about 35 days.
