How Long Do Shrimps Stay Pregnant? A Guide to Understanding Shrimp Reproduction

Diving into the world of aquarium shrimp, you may have plenty of questions related to their reproduction. How do the little critters breed, and how long does their pregnancy last? In this comprehensive guide, we’ll address these queries and more, providing you with valuable insights into the fascinating process of shrimp reproduction.

Shrimps reproduce in a unique way, with pregnancy durations varying depending on the species. To grasp the complexity of this phenomena, it’s essential to look into the details. After all, knowledge is power, and understanding the nuances of shrimp breeding will undoubtedly enhance your fishkeeping experience.

Eager to uncover the mystery of shrimp pregnancies? Without further ado, let’s dive into the shrimp reproduction journey, uncovering facts and insights that will leave you thoroughly enlightened.

How Long Do Shrimps Stay Pregnant?

The Magic Number

In general, shrimp pregnancies can last anywhere between 2 to 5 weeks, depending on the species. However, to gain a deeper understanding of this process, let’s first discuss two of the most popular species among aquarists:

  1. Cherry Shrimp (Neocaridina davidi): Cherry shrimp females typically carry eggs for about 2-3 weeks before releasing shrimplets.
  2. Amano Shrimp (Caridina multidentata): Amano shrimp have a slightly longer pregnancy period of 3-5 weeks.

It’s important to note that these are just estimates, and individual shrimp may exhibit variations in their reproductive timeline.

Reproduction Process

Reproductive Organs

Believe it or not, identifying a shrimp’s gender can be relatively simple. Males usually have smaller bodies and more vibrant colors, while females are larger and may have a curved underbelly to facilitate egg-carrying.


Shrimp mating occurs when males deposit sperm into the female’s genital pore, known as the thelycum. From there, the female begins producing eggs that eventually become fertilized and attached to her abdomen. This is also when a shrimp becomes “pregnant” or “berried.”

Giving Birth

Hatching Those Adorable Shrimplets

At the end of the pregnancy, small, fully-formed baby shrimp, known as “shrimplets,” emerge from the fertilized eggs. These shrimplets are tiny replicas of their parents, able to survive, eat, and grow without any additional parental care.

So, depending on the species, you can expect baby shrimp to appear anywhere from 2 to 5 weeks after successful mating. Voilà! Welcome your new shrimplets to the family.

Caring For Your Berried Shrimp

No Special Treatment?

While they’re pregnant, shrimp don’t require any unique care or accommodations. Just ensure their living conditions are up to par by maintaining optimal water quality and offering a balanced diet.

Safety Measures

To provide a safe environment for berried shrimp, consider adding hiding spots, such as plants or decorations, to your tank. This will offer protection to both the expecting mothers and their future offspring. Adequate coverage can also minimize stress levels, making it more likely for your shrimp to carry their eggs to term.

What Happens To Unhatched Eggs

Every now and then, you might notice your berried shrimp releasing a few unhatched eggs. This is a natural occurrence and usually indicates that the eggs are not viable. The shrimp will simply continue their reproductive cycle and lay another batch.
