A pregnant Amano shrimp is a beautiful sight. But before you can enjoy the beauty of these pregnant shrimp, you need to know how to care for them. However, this might be a difficult task for beginner shrimp enthusiasts.

Believe me. It is worth it in the end. You can have many colorful baby shrimp running around your aquarium with a little care.

In this guide, I will cover everything you need to know about caring for pregnant Amano shrimp. This includes their diet, habitat, and general care.

How Do I Know That My Female Amano Shrimp Is Pregnant?

A pregnant Amano shrimp will carry a visible clutch of eggs on her swimmerets, varying in color from dark green to brown or dark yellow.

The mother shrimp continually fans the eggs to keep oxygen circulating around them until they hatch.

What Are the Different Stages of Female Amano Shrimp Pregnancy?

To better understand how to care for your pregnant Amano shrimp, it is important to know the different stages of their pregnancy.

The first stage starts when the female shrimp is ready to mate, with her eggs visible through her carapace and her dorsal fin becoming swollen. At this point, she will be looking for a mate.

The second reproduction stage begins when the female shrimp releases a pheromone that will attract male shrimp. If you have more than one male, they may bicker during this period, but it seldom gets out of hand. Once the female has chosen a mate, it will wrap its body around hers in order to fertilize the eggs.

The third and final stage will begin when the female Amano deposits its eggs on its swimmerets, where it will keep them until they hatch. When a female has eggs on her swimmerets, she is said to be in the “berried” stage. The eggs will develop gradually, but you won’t notice much change.

What Are the Signs That Your Amano Shrimp Is Ready to Give Birth?

While female Amano shrimp typically carry their eggs for five weeks, there are other telltale signs that hatching time is near. For example, as the eggs get ready to hatch, their color lightens from dark green to yellow khaki. This change means that hatching is imminent.

Another method to anticipate when your female Amano will lay her eggs is to look for the eyes of the shrimp larvae through the egg with a magnifying glass. If they are, it’s only a matter of days until they hatch.

What Is the Best Way to Take Care of a Pregnant Amano Shrimp?

If your wife is pregnant, you will have to take on extra responsibilities to ensure she stays healthy and happy. This is also true for pregnant Amano shrimp. Here are some tips on how to care for your pregnant Amano shrimp:

Provide a Nutrient-Rich Diet

A pregnant Amano shrimp needs a diet that is high in nutrients in order to produce healthy eggs. A lack of nutrients can result in deformed or stunted shrimp larvae.

To ensure that your pregnant Amano shrimp gets the nutrients it needs, feed it a protein-rich diet. This can be in the form of live or frozen foods, such as brine shrimp, daphnia, or bloodworms. Also, you can supplement their diet with high-quality dry foods designed specifically for shrimp.

Keep Them Safe

The most crucial aspect to remember is that you must monitor a pregnant shrimp carefully to see when she’s about to lay her eggs.

You can lose the entire clutch if it’s exposed to saltwater, a brackish tank, or chemicals before laying its eggs.

So, allow your female shrimp to give birth in fresh water and only transfer the larvae (baby shrimps) into salt water or brackish water once they’ve hatched.

Also, keep in mind that pregnant shrimp are more vulnerable to predators. So, ensure their tank is well-secured and free of potential threats.

You can add extra plants or rocks to help provide some hiding spots.

How To Properly Take Care of Amano Shrimp Fry

Separate the Berried Female During Hatching

After the eggs lighten in color and you can see the shrimp larvae’s eyes with a magnifying lens, it’s time to begin the most difficult portion of breeding: getting newly hatched larvae into brackish water-rearing tanks.

When you’re confident that the eggs have begun to hatch, remove the berried shrimp from the breeding tank.

To avoid shocking the female, use water from the breeding tank instead of fresh water. The eggs will hatch in a few hours.

If you want to see the larvae, turn off all lights in the room and use a flashlight to shine onto the water’s surface. The larvae are attracted to light and swim toward your flashlight. This makes it easier for you to remove them into their rearing tank.

Before transferring the larvae, make sure you have prepared their tank by adding an air stone that is set at a low setting and placing a black background. Also, be sure that water within their new environment is already brackish.

If you don’t want to transfer the fry manually, you can remove the female instead and let the larvae drift into their rearing tank on their own. Ensure you’ve removed the adult female before proceeding with the salt.

Setting up a Healthy Larvae & Fry Tank

The Amano larvae cannot survive in water. Therefore, you must add 30 grams per liter for Amano shrimp larvae rearing.

To maintain proper oxygenation for the Amano shrimp fry, keep an air stone on at a low setting.

Also, live plants will help to create a more stable environment and help with the rearing process by providing oxygen and pure water for the fry shrimps.

You should always keep the tank’s temperature at 75 degrees Fahrenheit. However, it should never drop below 64 degrees Fahrenheit or exceed 80 degrees Fahrenheit.

As for pH levels, they should be between 7 to 7.5, and the water hardness levels should be at 7 to 8 ppm. Further, maintain the ammonia level as low as feasible and the nitrate level below 20ppm.

In addition, diatoms in natural water are very vital to them. They can get diatoms from light sources, so you should add a LED grow light and aim it at the fry tank.

Over the next two weeks, your Amano larvae will start to develop and appear legless. When they acquire a slight crimson coloration, you can be sure that your salinity is correct.

The Amano Shrimp Larvae Diet

Along with a stable environment, the Amano shrimp fry needs a proper diet to help them develop into healthy adults.

You can begin by offering them crushed spirulina flakes, but make sure you do it in a tiny powder form. Also, you may feed them a finely dosed brewer’s yeast preparation.

However, only put a tiny amount of food in the tank, as you don’t want to pollute the water.

The safest option is to give them microencapsulated fish fry food ranging from 30 to 120 microns for the initial few weeks.

Your Amano Shrimp Is a Grown-up Now!

Have your larvae reached 30 days old? If so, they are now juvenile shrimp. This could last anywhere from another 30 to 60 days.

During this stage, keep an eye on the shrimp and gradually bring the water salinity below 15ppt. Otherwise, the shrimp will die within two days!

In addition, you should feed them algae wafers and commercial solutions after completing this phase.

The fish can be transferred to another tank after 3-5 months with extreme caution. They will no longer be in danger of dying and can live for 2-3 years if all goes well.

Why Is My Pregnant Amano Shrimp Curling Up?

Pregnant Amano Scratching or Airing Out Eggs

When your Amano berried lady folds up, she’s most likely just giving herself a nice stretch and scratch. This is completely normal!

Also, she might be curling up to allow her swimmerets to operate when inflating the eggs. It’s critical to keep the water flowing around the eggs in order to avoid mildew.

Pregnant Amano Molting

If something happens to the mating process or eggs, a female Amano shrimp may molt whilst pregnant. Before molting, shrimp curl up to aid in breaking and shedding the old shell.

In addition, if a berried shrimp molts, there is a high probability that all of the eggs will die with the molted shell. Also, molting can be triggered by unhealthy water conditions, illness, or stress in the shrimp.


How Many Babies Do Amano Shrimp Lay?

The number of offspring that an Amano shrimp can have at one time ranges from 1000 to 3000 eggs.

To take care of all these eggs, the pregnant shrimp will fan them with her swimmerets to ensure they receive a steady oxygen supply.

Can Amano Shrimp Lay Their Eggs in Freshwater?

Amano shrimp can lay eggs in freshwater, but the fry will not survive unless the water conditions are nearly perfect. However, baby shrimp need a period of time in saltwater to develop properly.

Are Amano Shrimp and Yoyo Loaches Compatible?

They aren’t the best of friends, but they can coexist. The Yoyo loach will harass the Amano shrimp, and they may even eat your shrimp.

Can I Breed Amano Shrimp in a Community Tank?

It’s unlikely that Amano shrimp will breed in a community tank because they need specific water conditions. The fry also needs salt water to develop, which most community tanks don’t have.

Are Amano Shrimps Egg Layers?

Amano shrimp lay eggs, which they attach to their swimmerets. Once the eggs are fertilized, the pregnant shrimp will carry them around until they hatch.

How Long Do Amano Shrimp Carry Their Eggs?

Amano shrimp carry their eggs for about 5 weeks before they hatch. During this time, the pregnant shrimp will fan the eggs with her swimmerets to ensure they receive a steady oxygen supply.

Last Words

Pregnant Amano shrimp are a beautiful sight to behold, and they’re not difficult to care for if you know what you’re doing.

With the proper water conditions and diet, your pregnant Amano shrimp can successfully give birth to a large number of fry.
