CATDOLL : CATDOLL: When should guppy fry be separated into different tanks and how long should they be kept together?

After the guppies give birth, they should be separated immediately, or a funnel-shaped partition wall should be formed with plastic film, with the upper end fixed on the water surface and the lower end immersed in the water. The female fish should be placed in the funnel so that the fry can enter the water outside the funnel through the small hole of the funnel after they are born. This is because when the female fish is giving birth, other big fish will eat the newly born fry.

Generally, you can mix the peacocks when they start to grow colors.

Guppy growth and reproduction:

Guppies are ovoviviparous fish. They have strong reproductive capacity and early sexual maturity. After 3-4 months of breeding, young fish enter the mature stage and can reproduce offspring. The time of sexual maturity is closely related to the water temperature and breeding conditions. When breeding guppies, you should choose a larger aquarium and keep the water temperature at 26 degrees Celsius. The pH should be 6.8-7.4. At the same time, you should plant more aquatic plants and then put in breeding fish at a ratio of 1 male to 4 females. After the fish are in estrus, the abdomen of the female fish gradually swells and black fetal spots appear; the male fish constantly chases the female fish at this time, and the male fish's copulator is inserted into the female fish's cloaca to discharge sperm for internal fertilization. When the female fish's fetal spots become large and black and the anus protrudes, it can be scooped into another aquarium to give birth.

The temperature in the birthing box should be 1-2 degrees higher than the original water temperature. Put moss or water plants at the bottom of the box to provide a shelter for the small fish. After the female fish gives birth, it should be taken out immediately to avoid eating the fry. Alternatively, plastic sheets should be used to form a funnel-shaped isolation wall, immersed in water, and the female fish giving birth should be placed in the funnel so that the fry will fall into the water outside the funnel from the hole under the funnel after they are born, and the female fish will not be able to eat the fry.

You didn't say what kind of fish you raise, so the following is an introduction to the situation of guppies laying small fish for your reference.

Guppies are ovoviviparous, so breeding is very easy. The water temperature for breeding is 20-23 degrees Celsius. There is no need to select broodstock for breeding. They can mate during their growth. When the young fish grow to more than two months old, they will start to reproduce. I don't know when the female fish will become pregnant. In fact, the male fish starts chasing the female fish when it is very young. When the female fish's fetal spot changes from white to black and the anus protrudes, it is a sign of labor.

Second, when you find signs of labor, you should take the female fish into the breeding box. So you must prepare a breeding box, because when the female fish is giving birth, other big fish will eat the newly born fish. When the female fish is placed in a separate breeding box before giving birth, it will be extremely panicked and swim around quickly at first. When it finds that the new environment is very safe, you will see a warm and pleasant scene when you wake up tomorrow morning: dozens of young fish snuggling around the mother. However, due to the influence of the environment, such as the water temperature is too low, or the female fish feels that there are too many fish around and it is unsafe for the small fish, the female fish will postpone giving birth for the safety of her baby's life.

Female fish give birth to 20-40 fry each time, and some give birth to as many as 70-80 fry. After the fry are born, they will swim and forage, and they grow rapidly. The gender can be determined after 1 month, and they will mature after 4 months. The breeding cycle is about 1 month. Generally speaking, the mother fish will not devour her own children, but it is still necessary to raise them separately. In order to give the small fish a safe and leisurely environment, the mother fish should be put back to the original large fish tank after giving birth. It is to remove the mother fish, not the young fish!

3. The following are the baits and feeding methods for feeding young cubs for your selection.

1 Wrap the cooked egg yolk with gauze, twist it gently in the water and shake it slightly to make the egg yolk seep out slowly for the fry to eat. Note that it should be fed twice a day in small amounts to avoid polluting the water quality and causing the death of the fry.

2 When the fry can swim to the surface, start feeding them small fish worms (water lice). Small fish worms are small worms that are filtered out of the fish worms that have been caught using gauze or plastic mesh. When they grow to one or two centimeters long, you can feed them regular fish worms.

3 Thaw the frozen brine shrimp and grind them slightly before feeding.

4 Grind the artificial dry bait slightly and feed it to the fish.

5 Grind the dried red worms and feed them.

Four water change methods

Use a thinner plastic hose to siphon out the dirty water. Keep the water inlet as far away from the fish as possible. Do not change too much water at a time. It is appropriate to replace 1/4 to 1/5 of the water each time.

It depends on how big your breeding tank is. If it is small, you can separate the tanks after about half a month. When you separate the tanks, remember to use a spoon to scoop out the fish with the water. If they grow fast, they can enter the breeding period in more than two months. You can keep them in a mixed tank.

After the mother fish gives birth to the small fish, they need to compete for the tank. If you raise the small fish alone, you can raise them together when they are more than 1 cm. You can only raise them with fish of similar size, so try to raise them slightly larger.
