Hey there, fellow shrimp enthusiasts! I’ve been keeping aquarium shrimp for years, and one of the most exciting moments is spotting those tiny eggs under a female shrimp’s tail. Today, I’ll share everything you need to know about identifying shrimp eggs and ensuring they develop successfully
Quick Answer
Shrimp eggs appear as small, spherical balls, typically yellow to orange in color, carried under the female’s tail. They’re usually grouped in clusters of 20-30 eggs, looking like tiny berries (which is why we call egg-carrying females “berried shrimp”).
Detailed Guide to Identifying Shrimp Eggs
Physical Characteristics
- Shape: Perfect little spheres
- Size: Tiny (about 1mm in diameter)
- Location: Clustered under the female’s tail
- Appearance: Typically opaque when fertilized
- Number: Usually 20-60 eggs depending on species and shrimp size
Common Egg Colors by Species
| Shrimp Type | Egg Color |
|---|---|
| Cherry Shrimp | Bright yellow to orange |
| Ghost Shrimp | Pale yellow or greenish |
| Amano Shrimp | Light yellowish brown |
| Bamboo Shrimp | Dark brown to black |
The 4 Stages of Shrimp Egg Development
1. Initial Formation (Oogenesis)
- Eggs first develop in the female’s ovaries (visible as a “saddle”)
- Takes about 50-90 days for sexual maturity
- Temperature affects development speed
2. Fertilization Stage
After mating:
- Eggs move from ovaries to swimmerets
- Process takes 1-2 hours
- Female finds safe spot during this vulnerable time
3. Development Period
- Lasts 15-30 days depending on water temperature
- Eggs start opaque, become more transparent
- Two black spots (eyes) appear near hatching
- Mom fans eggs regularly for oxygen
4. Hatching Phase
- Baby shrimp emerge at about 3mm long
- Initially transparent
- Carry small yolk sacs for 5-8 days
- Begin independent feeding after yolk depletes
How to Care for Berried Shrimp
Do’s:
- Maintain stable water parameters
- Feed high-protein foods
- Keep water clean but avoid major changes
- Provide plenty of hiding spots
Don’ts:
- Don’t stress the mother
- Avoid sudden temperature changes
- Don’t overcrowd the tank
- Don’t overclean during egg development
Common Problems and Solutions
Dropping Eggs
If your shrimp’s dropping eggs, check:
- Water parameters
- Stress levels
- Tank temperature
- Protein intake
Unfertilized Eggs
You’ll know eggs aren’t fertilized if they:
- Look translucent rather than opaque
- Get ignored by the mother
- Fall off easily
- Appear pale or whitish
Tips for Successful Breeding
- Keep water parameters stable
- Provide plenty of plant cover
- Feed varied, protein-rich diet
- Maintain optimal temperature (72-78°F)
- Reduce stress factors
Final Thoughts
I gotta tell ya, watching shrimp eggs develop and hatch is one of the most rewarding experiences in the hobby! Just remember, patience is key – those little eggs need about 2-3 weeks to hatch. Keep the water clean, the momma happy, and before you know it, you’ll have tiny shrimplets swimming around!
For first-time shrimp keepers, don’t worry too much if things don’t go perfect right away It took me several tries before I got the hang of it Just focus on maintaining good water quality and providing a stress-free environment, and nature will do the rest!

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 4: Hatching & Juvenile Development
After fully developing, the juvenile shrimp break free of their egg to live life on its own! At hatching, baby shrimp—shrimplets—are about 3mm long and mostly transparent. They still carry a small amount of their yolk with them to prevent starvation over the first 5-8 days while they find shelter and sufficient food. After that, juvenile shrimp need a steady supply of food for the rest of their lives to continue growing. This typically comes in the form of detritus (dead plant/animal matter) and biofilm (bacterial growth). To encourage biofilm growth, we recommend using a bacterial powder like BacterAE in your tank. Click here to learn what BacterAE is made of and how the ingredients help your tank.
At this young age, shrimp grow rapidly, molting an average of 7 times within the first 20 days! As they get older, molting frequency decreases, eventually trailing off to once every 1-2 months once they hit adult size, at which point they reach sexual maturity and continue the lifecycle.
A newborn shrimp is about 3mm and mostly clear. This one just has a few spots of pigments!
Now you have a much better grasp on the fascinating process of how dwarf shrimp eggs develop. Remember that those early days are critical though. Good water quality and a sprinkling of BacterAE give shrimplets the best chance for a healthy start. Soon, these tiny creatures will be joining the adults, foraging, molting, and maybe even starting a new generation of their own.
When you see this amazing development for yourself, hopefully it sparks your curiosity and encourages you to ask more questions about shrimp and their environment.

How do shrimp eggs look like?
FAQ
Where do shrimp lay their eggs?
The female will release sexual hormones into the water when she is ready to breed. The male will then find her and deposit his sperm onto the female, who passes the eggs underneath her tail. The eggs stay there, constantly being fanned by the shrimp’s tail until they are ready to hatch.
What do baby shrimp eggs look like?
The eggs will often start off a bright color – orange or yellow – and get more translucent as they get closer to hatching. And like others have said, eyes, but I’m bad at spotting those personally.
How to identify shrimp eggs?
since it only happens when shrimps are ready to breed, but that is to look for a saddle or eggs. The saddle is a yellowish green spot on the back of the shrimp, while the eggs are tiny. yellowish green balls under the abdomen of the shrimp. If your shrimp either contains a saddle or eggs, they’re females.
How long does it take for shrimp eggs to hatch?
