Hey there! I’m Thomas, and today we’re gonna dive deep into the fascinating world of shrimp pregnancy. If you’ve ever wondered how long these little creatures carry their eggs, you’re in the right place. As someone who’s been keeping aquarium shrimp for years, I’m excited to share everything I know about this topic!
Quick Answer
Shrimp typically carry their eggs for 25-30 days before they hatch. The exact timing depends on the species and water temperature For example, Cherry shrimp eggs might hatch in just 20 days at 75°F, while Amano shrimp can take up to 35 days at 72°F
The Complete Shrimp Pregnancy Journey
Stage 1: Egg Development (The Saddle Stage)
When a female shrimp starts developing eggs, you’ll notice a yellowish, greenish, or brownish patch behind her head – we call this the “saddle.” This is actually her ovaries, where the unfertilized eggs are hanging out. Pretty cool, right?
Stage 2: The Mating Dance
This is where things get interesting! When a female’s ready to mate, she’ll release some pheromones that basically say “Hey boys, I’m available!” You might see males zooming around like crazy – that’s totally normal. The actual mating only takes a few seconds, but it’s crucial for fertilizing those eggs.
Stage 3: The Berried Stage
After mating, something amazing happens:
- The eggs move from the saddle to under the female’s tail
- They attach to special hair-like structures called swimmerets
- The female becomes “berried” (that’s what we call a pregnant shrimp)
- She’ll constantly fan her eggs to keep them clean and oxygenated
Different Species, Different Timelines
Here’s a handy table showing how many eggs different shrimp species typically carry:
| Species | Number of Eggs |
|---|---|
| Amano Shrimp | 1000-3000 |
| Tiger Shrimp | 100-300 |
| Cherry Shrimp | 20-30 |
| Ghost Shrimp | 10-80 |
| Crystal Red Shrimp | 20-30 |
Taking Care of Your Berried Shrimp
If you’ve got a pregnant shrimp. here’s what you should do
-
Keep the water perfect
- Maintain stable temperature
- Regular water changes
- Keep parameters consistent
-
Provide hiding spots
- Add plenty of plants
- Include some driftwood
- Create rock caves
-
Feed properly
- High-protein foods
- Blanched veggies
- Algae wafers
Common Problems and Solutions
Dropped Eggs
Sometimes shrimp might drop their eggs before they’re ready to hatch. Don’t panic! This usually happens because of:
- Stress from poor water conditions
- Harassment from other tank mates
- The female being inexperienced (first-time moms, ya know?)
What to Do If Eggs Are Dropped
If you notice dropped eggs, you can try to save them using a shrimp egg tumbler. Here’s how:
- Carefully collect the eggs
- Place them in a container with tank water
- Use an air stone to keep water moving
- Monitor temperature closely
Signs That Eggs Are About to Hatch
You’ll know the eggs are close to hatching when:
- They become more transparent
- You can see tiny black dots (baby shrimp eyes!)
- The female starts moving around more
- Color changes from dark to lighter
Some Common Questions I Get
Q: Do shrimp lay eggs or give birth?
A: They don’t exactly “lay” eggs – they carry them under their tail until they hatch!
Q: How often can shrimp have babies?
A: In good conditions, female shrimp can get berried every 4-6 weeks after reaching maturity.
Q: Can I move a berried shrimp to another tank?
A: Better not to – moving can stress them out and cause egg dropping.
Tips for Success
- Be patient! The waiting game is real
- Don’t mess with the berried female too much
- Keep water parameters super stable
- Provide lots of hiding places
- Watch out for aggressive tank mates
My Final Thoughts
Taking care of pregnant shrimp isn’t rocket science, but it does need some attention to detail. The most important thing is keeping their environment stable and stress-free. Trust me, there’s nothing more rewarding than seeing tiny baby shrimp swimming around your tank after a successful hatch!
Remember, every shrimp keeper was a beginner once, so don’t worry if things aren’t perfect right away. Just keep at it, and before you know it, you’ll have a thriving shrimp colony!
Why It’s Important To Understand Egg Development
Dwarf shrimp like neocaridina (i.e. red cherry, blue dream, green jade shrimp) and caridina (i.e. crystal red, blue bolt, black king kong shrimp) have a very interesting reproduction cycle. Like humans, they reproduce sexually so both a male and female are needed to make baby shrimp. Females also have similar anatomical parts like ovaries where eggs develop. Understanding the process of how dwarf shrimp eggs develop is really useful because it helps shrimp keepers identify what behaviors and appearances are normal – and those that arent. The rest of this article takes a look at the four steps in dwarf shrimp egg development so you know exactly what to expect when your shrimp breed! We also developed a tool that estimates the day eggs will hatch so you can be on the lookout for baby shrimp at the right time, which you can access here.

Stage 3: Embryo Development
Once eggs reach the swimmerets, they take anywhere from 15-30 days to develop in normal aquarium temperature ranges. Eggs typically start out as relatively opaque yellow spheres, but they can also be green, white, or even blue! It is not clear exactly what causes eggs to be different colors but most eggs in the clutch tend to be the same color, at least if they are all viable.
As the embryos mature, eggs become more translucent. You can often tell when eggs are within a few days of hatching because two tiny black spots will appear on the eggs. These are the developing eyes!
During egg development, the mother moves her swimmerets up and down at varying rates. This moves fresh water around the eggs so they stay oxygenated and (hopefully) free of infection. The most common problem during this phase is a white, fuzzy fungus that grows between the eggs, which happens when water quality is less than ideal.
