Most freshwater shrimp species, including cherry shrimp, carry fertilized eggs for 2 to 4 weeks before they hatch. The exact duration depends on species, water temperature, and tank conditions. During this time, the female fans and cleans the eggs under her abdomen to ensure proper development and oxygenation.
How Long Do Shrimp Carry Eggs?
Shrimp are fascinating aquatic creatures known for their unique reproductive cycle. After successful mating, the female shrimp carries fertilized eggs beneath her abdomen, also known as her swimmerets. The eggs remain there for several days to weeks depending on the species and environmental factors, especially water temperature.
In this guide, we’ll break down how long different shrimp species carry eggs, what influences the hatching period, and what to expect during each stage of the egg-carrying process.
Shrimp Egg-Carrying Duration by Species
| Shrimp Species | Egg-Carrying Duration | Hatching Timeframe | Notes |
| Cherry Shrimp | 2–3 weeks (14–21 days) | 20–28 days | Eggs are carried under the tail; hatch fully formed |
| Ghost Shrimp | 2–3 weeks | 20–25 days | May breed less consistently in captivity |
| Amano Shrimp | 3–5 weeks | Eggs need brackish water | Larvae hatch and need saltwater to develop |
| Crystal Red Shrimp | 3–4 weeks | 25–30 days | Sensitive to temperature and water quality |
| Neocaridina (general) | 2–3 weeks | 20–28 days | Includes cherry, blue dream, snowball shrimp |
| Sulawesi Shrimp | 4+ weeks | ~28–35 days | Require high temperatures and hard water |
Do Shrimp Lay Eggs or Give Birth?
Shrimp lay fertilized eggs, which the female holds under her tail until they hatch. They don’t give live birth. During this time, the female continuously fans the eggs with her swimmerets to keep them oxygenated and clean, which prevents fungus or rot.
Once the eggs hatch, most freshwater shrimp (like cherry shrimp) release fully formed miniature shrimp—no larval stage required. However, some species like Amano shrimp release larvae that require brackish or saltwater to survive.
Cherry Shrimp Egg Stages Explained
Cherry shrimp (Neocaridina davidi) follow a predictable breeding and hatching timeline under stable conditions.
1. Saddle Stage
- The female develops yellow or greenish eggs inside her body.
- Located behind the head—visible in lighter-colored shrimp.
2. Berried Stage (Carrying Eggs)
- Eggs move to the abdomen and become visible under the tail.
- Female uses swimmerets to keep eggs oxygenated.
- Lasts about 14–21 days, depending on temperature.
3. Color Change of Eggs
- Eggs start as light green/yellow.
- Turn darker (brown or grey) as they mature.
- Darker eggs are closer to hatching.
4. Hatching
- Baby shrimp (shrimplets) hatch fully formed and are released into the tank.
- No parental care needed—shrimplets feed on biofilm and microalgae.
How Long Do Cherry Shrimp Eggs Take to Hatch?
In optimal tank conditions (around 76°F / 24.5°C), cherry shrimp eggs hatch in 20 to 28 days. Colder water can extend this process, while slightly warmer temps can speed it up (but don’t go above 80°F as it can cause stress).
Do Shrimp Eggs Hatch All at Once?
Not exactly. While the eggs hatch over a short period, they rarely all hatch at the same moment. Hatching can take place over 1–2 days, with the female releasing shrimplets gradually as they’re ready.
Some females may retain a few eggs longer if the conditions aren’t quite right, which is normal.
How Long Do Ghost Shrimp Carry Eggs?
Ghost shrimp generally carry eggs for 2 to 3 weeks, and like cherry shrimp, they release fully formed baby shrimp. However, ghost shrimp are more sensitive to stress and water conditions, which may affect their ability to carry to term.
What Happens After Hatching?
Once the eggs hatch:
- The female resumes normal behavior and may molt shortly after.
- Shrimplets hide in moss, under leaves, or in sponge filters.
- Growth is fast if food is abundant—expect juveniles within a few weeks.
Feed powdered shrimp food, baby algae wafers, or biofilm-enhancing supplements to support the new generation.
Final Thoughts:
Knowing how long shrimp carry eggs and what happens during the process helps you provide the best care for your colony. While cherry shrimp and other Neocaridina types are the easiest to breed, every shrimp species follows a similar rhythm.
With stable water, a calm tank, and plenty of plants, your berried shrimp will thrive and soon fill your tank with tiny, fascinating new life.
