When can the young under a guppy be male and female?

1.Why are the hatchlings of my guppies all round in their tails?

The tail of the small larvae is round, and it will not come out until it is larger and has different tail shapes! (Just like the larvae of angelfish seem to be elongated, and the larvae of flounder have 2 sides of the glasses, you have to wait until they are older to distinguish them).

2.How long does it take to tell the male and female?

The juveniles are all the same, and they can't be distinguished! You can distinguish it in 2 weeks, because the male tail can be colored in about 2 weeks!

3.Are all the young born by female guppies female?

Of course not!

Guppy larvae can distinguish between male and female in a month and a half. About a month after the juvenile fish is born, the male will start to color, so look at the color of the fish first to confirm the male fish. When juveniles, the belly of the male is white, and the inside of the belly is not visible, but the female can see the color of the inside of the belly.

When it grows into an adult fish, it can be seen at a glance. The color of the male fish is more vivid than that of the female, and the fins of the male fish are relatively large, patterned and beautiful; The fins of the mother fish are short and do not have brilliant patterns. Guppies eat zooplankton, small insects and detritus and mainly insects, including midges, midges, house mosquitoes, dipters, homoptera, and hemipters.

At 3 weeks old, the normal development of juveniles can already be divided into male and female sexes, you can use this standard as a reference to see if your juveniles are raising up to standard. The juveniles I raise can be identified by the male and female at about 18 days old, but at this time, there is no need to rush to separate the male and female fish into separate tanks, and they can be separated together after waiting.

When the juveniles are 4 weeks old, if you want the fish to continue to develop well, grow large, and have outstanding strain characteristics, it is necessary to keep the male and female separately. Oh, because the male fish is so big will begin to chase the female fish dry "physical work", not good food and consume precious body energy, naturally thin and withered dry Yin Tang dark and no look, so sub-tank feeding is a must, which is also the key to breeding high-quality guppies!

I didn't feed the newborn fish that day, because one is to adapt to the environment first, and the other is that there is a yolk sac that has not yet been absorbed, hehe, the guppy is ovoviviparous. From the second day, it is best to open the mouth with live shrimp larvae, which are rich in nutrients and easy to absorb, and have the effect of promoting bowel movements. During this period, the fish can eat as much as possible and eat to the fullest, until the stomach is hemispherical, and a little live bait can be retained in the tank at this time.

The brother summed up a proverb: "Try to hold on for 4 weeks, feed hard in 2 months, eat enough for a month, and feed less after May". Since my brother has another job, he can only take time to feed about 2 times a day in the morning and evening, especially after feeding in the morning, it is better to keep a little live bait in the sub-fish tank. During this period, if according to the standards of professional players in Europe, America, and Japan, it should be fed 6 to 8 times a day, with an interval of about an hour between each time, so that professional players can refer to it.

When the fish have color on them! The male's belly has a color! The mother's tail has a color!

Generally speaking, as long as you ensure adequate nutrition and proper breeding, you can distinguish between male and female after a month and a half, and you will begin to enter the stage of sexual maturity in two months.

My family's 2 female guppies each gave birth to a litter, born to now more than a month or two or so I raised them separately because one of them is dystocia, only 3 small fish were born, and the other one gave birth to about 20 or so! I think that the time to distinguish between male and female has a lot to do with the sufficiency of food and the type of feed I have raised a tank of 3 fish for 1 month, and I can basically distinguish male and female, the male tail has a color earlier, and the body size is smaller than the female one (I observe it), and the female tail is now only a little bit of color The other tank may be a little dense, and the food is not sufficient, resulting in a few days earlier than the 3, and it is still impossible to distinguish the male and female, and only a few tails have begun to color I put them together with Daphnia since they were born, and let them hunt on their own, but then because they went on a trip, they didn't eat enough, so they grew a little slowly, but now I feed them Daphnia, water earthworms, mosquitoes and the like live and some bloodworms Now the growth is quite fast, and it is estimated that it will take up to another 3 weeks to distinguish between male and female

2.How long does it take to tell the male and female?

3.Are all the young born by female guppies female?

Method 1: Under normal circumstances, it is the male fish that starts to change color first, and the fish that changes color earlier is generally the male fish.

Method 2: You can see the back of the belly, the female can see the color of the inside of the belly, while the male fish has a white belly and cannot see the color inside.

The sex of juvenile guppies cannot be distinguished at birth, and even if they grow normally, it takes about a month to distinguish them. If it is still difficult to distinguish after more than a month of birth, it may be that the growth and development of small fish are slow due to poor food or water quality. At the same time, the gender discrimination of juvenile fish will also be affected by factors such as temperature, bait, strain, individual differences, etc., and it is normal for fast or slow to be about a week.
