Guppy Post-Birth Care

what to do after guppy give birth

Guppies are livebearers, which means they give birth to live, free-swimming young. After giving birth, the female guppy should be kept in a quiet tank to recover her strength before being reintroduced to the other fish. It's also important to provide a safe space for newborn guppies, as they are at risk of being eaten by other fish in the tank, including their mother. This can be done by creating a separate tank or closed-off area with floating plants and roots to provide hiding spots.

Isolate the mother guppy

It is important to isolate the mother guppy after she has given birth. This is because she will be tired and vulnerable after delivering the fry, and will need time to recover. Additionally, the mother guppy may eat her own offspring, so separating her from the newborns will increase their chances of survival.

There are several ways to isolate the mother guppy. One method is to use a separate breeding or birthing tank. This tank should be set up with a heater, a gentle filter, appropriate lighting, and hiding spots for the mother to rest and recover. The water conditions in the breeding tank should match those of the original tank to avoid shocking the mother guppy and causing unnecessary stress. The breeding tank also provides a safe space for the newborn fry, as they are at risk of being eaten by any fish species, including their mother.

Another option for isolating the mother guppy is to use a breeding box or net inside the normal tank. This will keep her separated from the other fish and give her a quiet space to rest. It is important to ensure that the breeding box or net is not too small, as this can cause stress for the mother guppy. It should also have enough plants or decorations to provide hiding spots and a comfortable environment.

When isolating the mother guppy, it is crucial to maintain clean water and stable water parameters. Stress due to inadequate water conditions can be detrimental to the health of the mother and the fry. Regular water changes, temperature checks, and maintenance of water quality are essential to providing a healthy environment for the recovering mother and her offspring.

It is also important to monitor the diet of the mother guppy during this time. A nutritious diet will help her regain her strength and recover from the exhausting process of giving birth. Offer her a variety of plant matter, invertebrates, and fish flakes to ensure she gets the necessary nutrients.

In addition to isolating the mother guppy, it is crucial to provide a safe environment for the newborn fry. They can be placed in a separate tank or bucket with water from the regular tank and plenty of plants for cover. Water lettuce is a good option as it can remove the need for a filter. The fry should be fed crushed or finely ground flake food until they are big enough to eat full-size flakes.

By isolating the mother guppy and providing a safe and healthy environment for her and the fry, you can ensure the best chances of recovery and survival for both the mother and her offspring.

Prepare a birthing tank

Preparing a birthing tank for your guppies is crucial to ensure the safety of the mother and the newborn fry. Here are some detailed instructions to set up a birthing tank:

Tank Size and Location:

Choose a tank that is at least ten gallons in size. Guppies are social fish and should be kept in schools. The general guideline is to provide at least one gallon of water per inch of fish. Place the birthing tank in a quiet and peaceful location, away from loud noises or bright lights that may cause stress.

Equipment and Decorations:

Install an external power filter suitable for your tank size. Add an air pump to oxygenate and circulate the water, and attach it to an action decoration like a treasure chest. Include a heater to maintain a temperature between 75-80 degrees Fahrenheit, with an adjustable thermostat. Use a light with a timer, providing an eight-hour dark period for the guppies to rest. Decorate the tank with rocks, live plants, and ornaments, ensuring they are firmly set in the gravel. These provide hiding spots for the guppies, reducing their stress levels.

Water Preparation:

Fill the tank halfway with water and add dechlorinator to remove harmful chlorine and chloramine. Then, cycle the tank by adding pure ammonia to develop beneficial bacteria. Test the water every other day, adjusting ammonia levels as needed. After a week, test for nitrites, which indicate the growth of bacteria consuming ammonia. Continue until ammonia and nitrite levels drop, and nitrate levels rise and stabilise.

Water Temperature and Maintenance:

Maintain a water temperature of 77-79 degrees Fahrenheit, optimal for guppy gestation. Use a gentle filter, such as a sponge filter, to avoid sucking up the newborn fry. Regularly clean the tank, performing water changes of 10-15% weekly, using fresh, dechlorinated water. Ensure the water is free of algae and perform a 25% water change every week to keep the tank clean and healthy for the fry.

Feeding the Pregnant Guppy:

Offer the pregnant guppy a nutritious and varied diet, including live or frozen brine shrimp, bloodworms, daphnia, high-quality flake food, and spirulina flakes. As the gestation period of 21-31 days approaches, monitor her behaviour for signs of impending birth, such as arched back, rapid breathing, and difficulty swimming.

Post-Birth Care:

After birth, remove the mother guppy to prevent cannibalism, as stressed aquarium fish may eat their young. Provide a separate recovery tank for the mother for a week or two. Remove any stillborn or weak fry, and feed the surviving fry with newly hatched brine shrimp, ground-up flake food, or commercial fry food.

Remember, the birthing tank should be well-cycled, with stable water parameters and temperature, providing a calm and safe environment for the mother guppy to give birth.

Protect newborn fry from predators

Guppies are livebearers, which means they give birth to live, free-swimming young. The baby guppies, called "fry", are immediately mobile and seek shelter within the aquarium. However, they are vulnerable to being eaten by adult guppies and other fish in the tank. Here are some ways to protect newborn guppy fry from predators:

Use a Temporary Container or Breeding Tank

If you don't have a separate breeding tank, you can use a larger glass jar or plastic container as a temporary haven for the pregnant female guppy when she begins the birthing process. Transfer her back to the main tank once she has finished giving birth.

Invest in a Breeding Box

If you cannot separate the pregnant female, a breeding box is a small mesh or plastic container that can be placed directly into the main tank. It allows water to circulate while keeping the fry safe inside. Once the female is done giving birth, remove her from the box, leaving the fry secure inside.

Create Hiding Spots with Live Plants

Enhancing the tank with live plants can significantly boost the survival chances of guppy fry by providing essential hiding spots. Plants like guppy grass, hornwort, java moss, and the roots of water lettuce can protect the fry for a couple of weeks, giving them time to grow stronger and more agile, reducing the risk from adult fish and other predators.

Use a Mesh Divider in the Guppy Tank

If you don't want to separate the mother and fry into a different tank, you can use a mesh divider in the guppy tank. This allows the fry to be in the same tank as the adults but keeps them separated and safe from being eaten.

Provide Ample Hiding Spots and Dense Vegetation

In addition to live plants, you can provide other hiding spots and decorations in the tank for the fry to seek refuge in. This could include rocks, caves, or driftwood. Floating plants can also provide cover for the fry.

Feed and care for newborn fry

Newborn guppies are extremely fragile and their survival depends heavily on your caregiving strategies. Here are some tips on how to feed and care for your newborn guppies:

Feeding

  • Newborn guppies can be fed live foods like Infusoria or artificial foods such as high-quality fry food.
  • Feed them multiple times a day but in small portions to avoid overfeeding.
  • For the first 1-2 weeks, newborn guppies mainly eat algae. After about 1-2 weeks, supplement their diet with pellets suitable for their age.
  • Ensure the water quality is excellent during this phase. Poor quality or contaminated water can stress the newborn guppies and harm them.

Water Conditions

  • Frequent water changes are essential, along with maintaining the optimal temperature and a stress-free environment.
  • The water temperature should be between 72-79 degrees Fahrenheit.
  • Clean the tank regularly to prevent the buildup of waste, which can make the fry sick.
  • Do a 25% water change weekly and add a sponge filter to your tank to ensure the fry do not get stuck in the filter.
  • Alternatively, attach a fish net over the filter opening to allow water to pass through while keeping the fry safe.

Hiding Spots

  • Provide plenty of hiding spots using plants and small caves to protect the newborn guppies from potential predators.
  • Keep in mind that fry can still be eaten, so consider using a separate tank or a closed-off area in the tank for added protection.
  • Floating plants with roots can offer a hiding place, and plants can be real or plastic.
  • Clump the plants together to give the fry a safer place to hide.

Lighting

  • Ensure the fry get enough light, which is necessary for optimal healthy growth.
  • Approximately 8 to 12 hours of light per day is sufficient, and you can use a tank light or ambient room light if it's bright enough.

By following these guidelines, you can provide the necessary care and feeding for your newborn guppy fry to ensure their health and well-being.

Maintain water conditions

Maintaining good water conditions is crucial for the health and well-being of both mother guppies and their fry. Here are some detailed steps to ensure optimal water parameters:

Water Temperature

Guppies prefer warm water, so it is essential to maintain a temperature between 72°F and 82°F (25°C and 28°C). This temperature range mimics their natural habitat and encourages optimal breeding conditions. In colder water, the pregnancy will last longer.

PH Level

Guppies thrive in slightly alkaline water with a pH range of 7.0 to 8.0. Regularly test the pH level using a reliable aquarium test kit and make necessary adjustments using pH buffers or conditioners.

Water Hardness

Guppies prefer moderately hard water, with a hardness range between 8 and 12 dGH (degrees of general hardness). You can achieve the desired hardness level by adding appropriate mineral supplements or adjusting the water source.

Regular Water Changes

Regular water changes are essential to maintain water quality and remove any accumulated toxins. Aim for weekly partial water changes of around 20-30% to ensure a clean environment for the pregnant guppy and her fry.

Ammonia and Nitrite Levels

Keep ammonia and nitrite levels at zero by performing regular water changes and maintaining proper filtration. High concentrations of these substances can be harmful to the fry.

Filtration

A reliable filtration system is crucial to remove waste and toxins from the water. Choose a filter that suits the size of your aquarium and ensure it is properly maintained and cleaned regularly.

Oxygenation

Adequate oxygenation is vital for the well-being of newborn guppies. Use an air pump or ensure proper surface agitation to maintain optimal oxygen levels in the water.

Light

Guppies require approximately 8 to 12 hours of light per day for optimal growth. You can use a tank light or ambient room light if it is bright enough.

Cleanliness

Keep the tank clean and free from algae. Perform a 25% water change weekly and clean any signs of algae buildup. This will help prevent the fry from getting sick.

Sponge Filter

Consider adding a sponge filter to your tank to ensure the fry do not get stuck in the filter. Alternatively, attach a fish net over the filter opening to allow water to pass through while keeping the fry safe.

Hiding Spots

Provide ample hiding spots for the guppies by adding live or artificial plants, caves, or rocks. These hiding places offer shelter and protection from potential predators in the tank.

Breeding Box

If using a breeding box, ensure it is spacious and has small holes or slits for water circulation. Attach a sponge filter or air stone to provide oxygenation and maintain water quality.

Frequently asked questions

After giving birth, the female guppy should be kept in a quiet tank for at least several hours so she can recover her strength before joining the rest of the fish. During this time, she should be well-fed to aid her recovery.

The baby guppies, also known as "fry", are at risk of being eaten by other fish in the tank, including their mother. To protect them, you can place a variety of floating plants with roots near the birthing tank or throughout the tank where the fish will live. Ideally, keep the plants clumped together to give the fry a safer place to hide.

Crush a tiny pinch of flake food very finely and give them that until they get big enough to eat full-size flakes.

If their care is excellent, female guppies can become pregnant once a month.

You will notice that the belly of the female guppies will expand. You can also observe a significant change in the colour and size of their pregnancy spots, which are usually darker and more prominent when they are pregnant.
