How often do black Mary fish breed?

Black Mary fish is an ovoviviparous fish, and the black Mary fish has a strong reproductive ability, and can reproduce once every 4 6 weeks, giving birth to 10 50 larvae each time; Just after giving birth to larvae, females need to rest alone for about a week, raising and breeding some precious species of black Mary fish, it is more difficult, mainly to ensure excellent living conditions, keep the water fresh, but can not often add a large amount of new water.

Black Mary is an ovoviviparous fish that is sexually mature at the age of 5 to 6 months. Black Mary fish are suitable for breeding in groups.

That is, in a larger aquarium, a variety of aquatic plants, 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.

Black Mary matures at 6 months of age and can reproduce once every month.

Black Mary fish have a strong reproductive ability, can reproduce every 4 to 6 weeks, each time to lay 10 to 50 larvae, just after the rise of the larvae, the female needs to rest alone for about a week.

1. Black Mary is an ovoviviparous fish with sexual maturity at the age of 5 to 6 months.

2. It is advisable for black Mary fish to reproduce 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 28 degrees Celsius, strengthen daily management, and find that there are larvae and fish out for another raising.

3. If the bottom of the aquarium is spread with large eggs, the newly born larvae may hide in the cracks of the stone to avoid swallowing by the female.

4. The newly laid larvae are dark black, turn gray after a few weeks, and turn black after chasing.

6. It is more difficult to raise and breed some precious varieties of black Mary fish. The main thing is to ensure excellent living conditions, keep the water fresh, but can not often add a large amount of new water, add a small amount of salt when changing the water, feed more palatable plant bait, precious species of fish fecundity is weak, the number of litters is small, generally in 10 to 30, the time interval between hatchlings should be longer.

Black Mary fish reach sexual maturity in 5 to 6 months and reproduce almost once a month, some may breed once a half month, and can reproduce and spawn 4 7 times a year, and can lay 10 200 small fish each time. The water temperature is controlled at around 25 to 28 degrees Celsius during the breeding period of black Mary fish, and the water quality must be kept clean. Black Mary fish begin to mature sexually at the age of 5 to 6 months, and reproduce almost once a month after reaching sexual maturity, and some Black Mary fish may reproduce once a month and a half, and can reproduce and spawn 4 7 times a year, and can lay 10 200 small fish each time.

If the water temperature does not reach the required level during the breeding period of the black Mary fish, the breeding cycle may be delayed, so during the breeding period of the black Mary fish, the water temperature needs to be controlled at about 25 to 28 degrees, and the water quality needs to be clean.

At this time, we need to prepare plenty of food for them, and also take care to protect their young pups from being swallowed by some large black Mary fish. Pregnant black Mary fish need to be kept separate from other fish, and the hatchlings need to be separated from the female.

The breeding cycle of black Mary fish is about 4-6 weeks. In the right environment, they can reproduce once a month. If the environmental conditions are not very suitable, the reproductive cycle will become longer.

If the environment is poor, they may not be able to reproduce. Newborn fish do not have the ability to reproduce, and it takes about 5 months to grow before they can reproduce. The first litter usually produces 10-50 small fish.

After that, they will grow and the number of small fish that reproduce per litter will increase. <

The breeding cycle of black Mary fish is about 4-6 weeks. If the breeding environment is suitable for breeding, then they can reproduce every 4 weeks. If the reproduction is slightly worse, then the reproduction cycle will become longer. If the environmental conditions are poor, then there is a chance that they will not be able to reproduce.

Generally speaking, black Mary fish grown in a suitable environment have the ability to reproduce after about 5 months of growth. There are some precocious individuals that may grow for about 4 months before reproduction. However, in actual farming, it is more recommended to select individuals with a growth time of more than 6-8 months as broodstock for breeding.

This results in better quality fry.

3. What environment is the black Mary fish suitable for breeding?

1. Water temperature: The water temperature range suitable for the breeding of black Mary fish is 25-28. Higher water temperatures are more conducive to juvenile growth. If the water temperature is very low, their reproductive cycle will become longer.

2. Aquatic weeds: Black Mary fish are more suitable for breeding in tanks with aquatic weeds. This is because aquatic weeds can provide shelter and help newborn juveniles avoid risks.

3. Water quality: When breeding black Mary fish, water with moderate hardness and weak alkaline should be used. This water is more suitable for juvenile fish growth.
