Hey there fellow aquarium enthusiasts! If you’ve noticed your ghost shrimp carrying eggs and wondering about their pregnancy duration you’re in the right place. As someone who’s bred ghost shrimp for years, I’m excited to share everything you need to know about ghost shrimp pregnancy and care.
Quick Answer
Ghost shrimp are typically “pregnant” (technically called gravid) for about 2-3 weeks. During this time, they’ll carry their eggs under their tail until they hatch. However, the exact duration can vary depending on water temperature and tank conditions.
Understanding Ghost Shrimp Pregnancy Stages
Week 1
- Small green dots appear on the female’s saddle near her abdomen
- Minimal behavior changes
- Female starts fanning her legs occasionally
Week 2
- Eggs move down towards the tail area
- Color lightens slightly
- Males typically fertilize eggs during this period
- Eggs become more visible and larger
Week 3
- Fertilized eggs turn whitish
- Black spots (eyes and stomachs) become visible in eggs
- Hatching occurs at the end of this week
How to Tell If Your Ghost Shrimp Is Pregnant
Here are the main signs to look for
- Green Specks: Look for tiny green dots near the abdomen
- Leg Fanning: Pregnant females fan their legs more frequently
- Tail Area: Eggs migrate towards the tail
- Weight Gain: Female appears notably larger
- Male Attention: Increased interest from male shrimp
Caring for Pregnant Ghost Shrimp
Tank Setup
| Parameter | Recommended Range ||-----------|------------------|| Temperature | 72-82°F (22-28°C) || pH Level | 7.0-8.0 || Tank Size | 10+ gallons |Essential Care Tips
-
Diet
- Provide high-quality shrimp food
- Offer varied diet including:
- Algae
- Plant matter
- Small protein sources
- Feed small amounts every 2-3 days
-
Water Quality
- Keep tank clean
- Use sponge filter
- Regular water changes
- Maintain stable parameters
-
Environment
- Add plenty of plants
- Provide hiding spots
- Keep stress levels low
- Remove aggressive tank mates
Common Challenges and Solutions
Problem 1: Dropping Eggs
Sometimes pregnant ghost shrimp might drop their eggs due to stress. To prevent this:
- Maintain stable water conditions
- Avoid sudden changes in parameters
- Provide adequate hiding places
- Keep tank mates peaceful
Problem 2: Egg Care
If you notice eggs turning different colors:
- Green = unfertilized
- White = fertilized
- Black spots = developing embryos
- Black = ready to hatch
Baby Ghost Shrimp Care
Once your ghost shrimp gives birth, here’s what you need to do:
-
Nursery Tank Setup
- Separate tank recommended
- Sponge filter only
- Lots of plants
- Fine substrate
-
Feeding Schedule
- Feed every 3 hours
- Use liquid fry food
- Provide microworms
- Add baby brine shrimp
Pro Tips from My Experience
-
Don’t panic if you can’t see the babies immediately – they’re super tiny and transparent!
-
I’ve found that adding a bit of Indian Almond Leaf helps create a more natural environment and provides microorganisms for the babies to feed on.
-
Keep your pregnant ghost shrimp in slightly warmer water (around 78°F) – it seems to help with successful hatching.
FAQs
Q: Will my ghost shrimp die after giving birth?
A: Nope! Unlike some creatures, ghost shrimp can have multiple successful pregnancies if properly cared for.
Q: How many babies can a ghost shrimp have?
A: Usually between 8-80 babies per pregnancy, tho I’ve seen some super mamas have even more!
Q: Can ghost shrimp breed in community tanks?
A: Yes, but survival rates of babies will be pretty low due to predation.
Final Thoughts
Breeding ghost shrimp isn’t rocket science, but it does require some attention to detail. The key is maintaining stable conditions and providing proper nutrition during the 2-3 week pregnancy period. With proper care, you’ll soon have a tank full of tiny transparent friends!
Remember, every shrimp keeper’s experience is different, and what works for me might need tweaking for your setup. Don’t be afraid to experiment (within reason) to find what works best for your shrimpies!
Happy shrimp keeping!

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.
