Hey there fellow aquarium enthusiasts! I’ve been keeping ghost shrimp for several years now, and one of the most common questions I get is about their pregnancy duration. Let me break down everything you need to know about ghost shrimp pregnancy based on my experience and research.
Quick Answer
Ghost shrimp are typically pregnant for 2-3 weeks (20-24 days) depending on water temperature and conditions. The warmer the water, the faster the eggs develop.
How to Tell If Your Ghost Shrimp is Pregnant
Before we dive deeper here’s how to identify a pregnant ghost shrimp
- Look for green or yellowish eggs under their belly
- The female will appear larger than usual
- She might move slower and hide more often
- You’ll notice tiny dots (eggs) between her swimming legs
- The eggs will get progressively greener as they develop
The Pregnancy Journey: Week by Week
Week 1
- Eggs appear as small whitish or pale green dots
- Female carries approximately 20-30 eggs
- Mother still active but might eat less
Week 2
- Eggs turn darker green
- You might see movement inside the eggs
- Mother becomes more protective
Week 3
- Eggs become almost transparent
- Baby shrimp features become visible
- Hatching occurs around this time
Caring for Pregnant Ghost Shrimp
To ensure successful breeding here’s what you should do
-
Water Parameters
- Temperature: 72-82°F
- pH: 7.0-7.8
- Keep water clean and stable
-
Diet During Pregnancy
- Feed small amounts every 2-3 days
- Suitable foods:
- Algae wafers
- High-quality shrimp food
- Frozen bloodworms
- Plant matter
-
Tank Setup
- Provide plenty of hiding spots
- Add live plants
- Use sponge filters to protect babies
- Maintain good water quality
Common Problems and Solutions
Problem 1: Dropping Eggs
Sometimes pregnant shrimp might drop their eggs before they’re ready. This usually happens due to:
- Stress from moving
- Poor water quality
- Lack of nutrients
- Temperature fluctuations
Problem 2: Egg Development Issues
If eggs aren’t developing properly, check:
- Iodine levels (add a drop of marine iodine during water changes)
- Water parameters
- Food quality
After Birth: What to Expect
Once the babies hatch:
- They’ll look like tiny transparent versions of adults
- They need lots of hiding places
- They’ll eat microscopic organisms in the tank
- Growth takes about 3-5 weeks to reach juvenile stage
Pro Tips from My Experience
- Don’t move pregnant shrimp if possible
- Keep other fish away – they might eat the babies
- Add moss or dense plants for baby survival
- Maintain stable water conditions
- Don’t panic if you don’t see babies right away – they’re really good at hiding!
FAQs
Q: Will the mother die after giving birth?
A: Not necessarily, but wild ghost shrimp typically live only about a year and might die after spawning. In captivity, with proper care, they can survive multiple pregnancies.
Q: How many babies can I expect?
A: Usually 20-30 eggs per pregnancy, but not all will survive to adulthood.
Q: Should I separate the pregnant shrimp?
A: It’s not necessary unless you have aggressive tank mates. A well-planted tank provides enough protection.
Conclusion
Ghost shrimp pregnancy isn’t super complicated, but it does require some attention to detail. The key is maintaining stable conditions and providing good nutrition. I’ve found that the most successful births happen in well-established tanks with plenty of plants and hiding spots.
Remember, every shrimp is different, and sometimes things don’t go as planned. Don’t get discouraged if your first attempt isn’t successful – it’s all part of the learning experience!

How do ghost shrimp breed?
Most shrimp breed in a similar manner, and ghosts are no exception. Once the female is ready to mate, shell molt and release pheromones that attract the males. Youll usually know this is happening because the entire tank seems to go a little crazy, with the shrimp zooming all over the place.
After mating, the female moves the fertilized eggs from her “saddle” (the colored patch behind the head) to her pleopods (back legs). She is now “berried”. Shell keep the eggs in her pleopods, gently waving them for oxygenation and regularly cleaning her brood, for up to 2 weeks.
If you set up a separate rearing tank as we recommended, you can transfer the female at around the 1-week mark (dont do it after hatching, as the larvae are very difficult to catch). Move her back once shes dropped the eggs.
The eggs will be carried in the females pleopods until they hatch. Theyre small, oval, and greenish to yellowish in color. When theyre almost ready to hatch, youll actually be able to see the tiny eyes of the larvae.
How do you tell the difference between male and female ghost shrimp?
In addition to the equipment, youll need a few ghost shrimp to start your colony. If you get 6-10, you can be pretty sure there are both males and females in the batch. It can be difficult to tell the difference between them at first, especially if the females arent carrying eggs yet, but youll soon get a feel for it.
Female ghost shrimp are larger than males. They will have a colored fleck behind the head, called a saddle, which are eggs developing in the ovaries. Alternatively, they might carry fertilized eggs in their swimmerets.
