Do Cherry Shrimp Lay Eggs? A Guide to Cherry Shrimp Reproduction
Cherry shrimp are a popular freshwater aquarium shrimp prized for their bright red coloration. An interesting feature of cherry shrimp is that, unlike most fish kept in home aquariums, they do not give live birth. Instead, cherry shrimp lay eggs which then hatch into larvae that mature into juvenile shrimp. Understanding the cherry shrimp reproductive cycle and how they lay eggs is key for breeding these ornamental shrimp. In this article, we’ll provide a complete guide covering topics such as:

Do Cherry Shrimp Lay Eggs?
Yes, cherry shrimp do lay eggs. They are oviparous, meaning they reproduce by laying eggs externally rather than giving live birth.
The female cherry shrimp carries the eggs attached underneath her body. There they are fertilized by sperm deposited by the male shrimp during mating. The female fans and aerates the eggs regularly until they hatch into free-swimming larval shrimp.
Cherry shrimp eggs must be fertilized by a male shrimp in order to develop. An unfertilized cherry shrimp egg will simply be discarded by the female after a short period.
What Do Cherry Shrimp Eggs Look Like?
Cherry shrimp eggs are small, oval-shaped, and range in color from greenish-blue to pale yellow. They are around 1.2 mm long on average.
The eggs are attached in grapelike clusters to the female’s pleopods (swimmerets) by thin filament-like strands. The filaments and egg membranes are transparent and difficult to see. So the eggs may appear to be loosely clustered rather than strung together.
You’ll notice the eggs as a colored patch under the body of a berried (egg-carrying) female shrimp. The saddle or back area where the eggs are carried will be darker in color.
Stages of Cherry Shrimp Eggs
There are 4 key stages in the development of cherry shrimp eggs:
-
Egg formation – Eggs grow within the female’s ovaries, seen as a colored patch behind the head.
-
Egg laying – Eggs move from the ovaries down to the swimmerets to be fertilized. The saddle darkens as it fills with eggs.
-
Berried stage – Fertilized eggs develop attached to the swimmerets. The female fans them constantly.
-
Hatching – After 3-4 weeks, the larvae hatch from the eggs and become free-swimming.
How Often Do Cherry Shrimp Lay Eggs?
Cherry shrimp can breed year-round but are most prolific in summer. Under ideal conditions, females can become berried every 4-6 weeks.
But in a typical home aquarium, breeding frequency is lower, with females producing a clutch of eggs every 2-3 months on average.
Key factors influencing cherry shrimp reproduction include:
- Water parameters – ideal pH 6.5-7.5, temperature 70-80°F
- Diet – well-fed shrimp breed more often
- Tank conditions – clean water, stable parameters
- Presence of males – females need access to males to breed
How Many Eggs Do Cherry Shrimp Lay?
A single female cherry shrimp may carry 20-30 eggs at one time. Larger adult shrimp tend to produce more eggs per clutch.
The actual number of larvae successfully hatching can vary and is generally lower than the number of eggs produced. This is because not all eggs may be properly fertilized or develop fully.
How Long Do Cherry Shrimp Eggs Take to Hatch?
Cherry shrimp eggs hatch after an incubation period of 2-4 weeks. The exact time frame depends mainly on the water temperature. Warmer temperatures within the ideal range speed up the hatching process.
You’ll notice the egg color darkening to brown as the embryos inside develop. When ready to hatch, tiny eyes will be visible inside the transparent eggs.
Where Do Cherry Shrimp Lay Eggs?
Unlike most fish which release eggs into the open water, cherry shrimp carry their eggs attached to the body.
After mating, the sperm is stored internally by the female until her next molt. The eggs are laid and move down to adhere to the swimmerets under the tail. Here they are fertilized by the stored sperm and remain until hatching.
The female constantly fans the egg clutch to oxygenate the embryos and keep them clean. She will seek out sheltered spots in the aquarium to do this undisturbed.
How to Identify Fertilized vs Unfertilized Eggs
It’s easy to tell if a shrimp’s eggs have been fertilized by looking at their location:
-
Unfertilized eggs remain in the saddle (ovary area).
-
Fertilized eggs have moved down to the swimmerets.
Any egg mass being actively fanned under the tail has been fertilized. If you see eggs still up on the saddle, they are immature eggs that have not yet been laid or fertilized.
What Happens if Eggs Are Left Unfertilized?
Without fertilization by a male shrimp, the eggs will simply be discarded by the female after a short time. She may eat the unfertilized eggs to reabsorb the nutrients.
An unfertilized egg will never develop into a shrimp larva or baby. So a female-only tank will never produce offspring. Introducing male shrimp is necessary for breeding and hatching viable eggs.
Will Dropped Eggs Still Hatch?
Cherry shrimp eggs that have fallen from the female’s swimmerets to the tank bottom will not continue developing.
Dropped eggs indicate a problem with the female shrimp. This could be due to stress, poor water quality, or a health issue. The embryos in dislodged eggs usually die quickly without the female’s constant care.
To hatch successfully, cherry shrimp eggs must remain attached to the female until the larvae are ready to emerge. So dropped eggs can be removed from the tank as they will not survive.
How to Save Cherry Shrimp Eggs
If the female shrimp dies unexpectedly, it may be possible to save the attached eggs and raise the larvae. Remove the dead female and continue aerating the egg clutch in a breeder box or separate tank. The larvae should hatch within a few days if the eggs were close to maturity.
Once hatched, the tiny shrimp larvae can be fed infusoria or powdered fry food several times a day. With ideal rearing conditions, some of the larvae may survive to adulthood.
Key Tips for Breeding Cherry Shrimp
- Start with 10-20 adults for best breeding results
- Keep parameters stable with weekly water changes
- Supplement their diet with calcium and protein
- Provide plenty of hiding spots with moss or plants
- Remove dropped eggs which will not be viable
Follow these best practices, and your cherry shrimp should reward you with frequent batches of eggs and larvae. Let us know if you have any other questions about cherry shrimp reproduction and egg laying!
How often do cherry shrimp lay eggs?
Shrimps can hatch eggs around every 30 days. After birth, shrimp are fully mature after four to six months and are able to breed. From then on, females are able to breed continuously over their lifetime. If your shrimp’s tank stays healthy and they’re not stressed by other things in the environment, they could theoretically have babies every month.
How many eggs do shrimp lay?
If fully fertilized, female shrimp can have up to 20-30 babies at a time. A few eggs may be dropped by accident or because they are stressed while they are carrying the babies, but if everything goes as planned, you can have a lot of shrimp babies!
Do Red Cherry Shrimps Lay Eggs?
Do cherry shrimp lay eggs?
Yes, cherry shrimp lay eggs. They do not give birth to live young. The female cherry shrimp will carry her eggs under her abdomen for about 2-3 weeks until they hatch. The eggs are initially clear but will turn dark brown or black as they mature. The female will fan the eggs with her swimmerets to keep them oxygenated and clean.
Can cherry shrimp breed in freshwater aquariums?
Interestingly, Cherry shrimp can breed in freshwater aquariums. When a female Cherry shrimp becomes berried (which means carrying eggs), she carries her eggs under her tail. During that stage, it’s essential to insert a pre-filter sponge to prevent the baby shrimps from being sucked into the filter when they hatch out of their eggs.
Do cherry shrimp mate?
In the case of cherry shrimp, the female shrimp will mate with a male shrimp, and the eggs will be fertilized during breeding. What do cherry shrimp with eggs look like? Cherry shrimp eggs are small and transparent. They are usually attached to the female shrimp’s abdomen, forming a cluster.
How long does it take for cherry shrimp eggs to hatch?
It generally takes 2 or 3 weeks for cherry shrimp eggs to hatch. The exact time might vary depending on the water temperature and other environmental conditions. How can I breed red cherry shrimp? You will need male and female shrimp to breed red cherry shrimp.
