Once the mother shows signs of being pregnant, you have between 24 and 30 days to make accommodations for your new fry. Once the mother gives birth, you can expect to have 20-40 new fry on average. The number can go up as high as 80 fry per day.
It depends on many factors, including the size of the fry, the amount of time it takes to grow, and the temperature of your fry’s environment. If you have a large fry that you want to keep, it may take up to two years for it to fully mature.

How long is a platy fish pregnant?
The eggs inside the female Platy’s belly will start to develop after fertilization. You will begin to notice your female fish’s belly becoming larger as the pregnancy progresses, since the duration of a platy pregnancy is around one month. Platy eggs are laid on the bottom of the aquarium and will hatch in about a week.
Once the egg hatches, it will continue to grow until it reaches a size of about 1.5 inches (3 cm) in length. At this point the fish will begin to eat the placenta, which will then be absorbed by the body. This process will take about two weeks to complete. After this process is complete, your fish should be ready to be released back into the wild.
When should I separate my pregnant platy?
The main purpose of separating a pregnant Platy from the rest of the fish is to ensure her safety against aggressive tank mates during her condition (and her fry if you choose to).
Why do platys eat their babies?
Platy fry can swim as soon as they are born. Adult platies don’t have any protective instinct toward fry; in fact, they may eat them. It’s important to remove the fry from the aquarium as soon as possible after they’re born. If you’re not sure if your platy is a fry or an adult, you can check the back of the head with a pair of tweezers.
Do platies give birth all at once?
The fry are born one at a time, tail first. A female can give birth to as many as 40 fry in a normal batches. Do not be surprised if the process goes on for a long time. Once the fry have hatched, they will stay with their mother until they are old enough to fend for themselves, at which point they leave the nest and begin to explore the world around them.
What do you do with a pregnant fish?
Once she releases the fry, she is returned to the main tank and the fry can be reared in the same way.
How many platies should be kept together?
A group of three to six platies is a good starting point. To give the group the best chance of survival, try to keep at least two females for every one male.
Platies can live for up to 10 years, but it is not uncommon for them to die before they reach that age. If you are planning on keeping a platy, be sure to check with your vet to make sure they are healthy enough to survive.
Why do fish eat their babies?
According to some, filial cannibalism is a result of a spill-over response prompted by stress factors, which enhances the self-preservation instinct of fish. This isn’t a satisfactory explanation because the same behavior can be observed in fish that aren’t kept in captivity. In a study published in the Proceedings of the Royal Society B, researchers from the University of California, Santa Barbara, and the National Oceanic and Atmospheric Administration (NOAA) investigated the effects of stress on fish behavior.
They found that fish exposed to stressful conditions were more likely to cannibalize each other than those that weren’t. The results suggest that stress may be a key factor in this behavior, but it’s not the only one. Other factors may also play a role, such as the amount of food available to the fish, the size of their tank, or the type of tank they’re in.
Do pregnant fish lay on bottom of tank?
Before giving birth, pregnant females may lay on the bottom of the tank. This is a good time to check on your fish and make sure they are doing well.
What do newborn baby fish eat?
The fry should be fed a quality food, such as baby brine shrimp, baby fish food, or quality flake food ground into a fine powder. The fry should be fed small amounts several times a day. Water quality can be maintained by performing regular water changes. Fry can be kept in the aquarium for up to 6 months, depending on the size of the tank.
What do platy fry eat?
Ensuring a varied diet consisting of both plant and animal-based foods is essential to help platy fry grow into strong and healthy adults. You can also feed them egg yolk paste, baby brine shrimp, bloodworms, and other things. Platy Fries are also a great source of calcium, magnesium, iron, zinc, manganese, copper, selenium, vitamin B12, and vitamin D3. They also contain a good amount of omega-3 fatty acids, such as DHA and EPA.
