I purposely bought a berried shrimp some days ago. It adapted well to my tank.
All of a sudden I just realized there are no eggs on the shrimp, and no shrimplets swimming around.
What could have happened?
The eggs may have hatched and the shrimplets are hiding somewhere in the tank (or got drawn into the filter if your intake doesn't have a fine pore sponge guard).
If there are small fishes in the tank, they might have eaten up most of the shrimplets too.
In some cases, the berried shrimp may also have dropped its eggs due to the stress of introduction into a new tank environment.

In addition to what UA have shared, assuming the shrimplets were hatched and not disappeared due to those reasons, try to wait for 2-3 days.Originally Posted by hardscape
It happened to me as well.
All of a sudden the eggs disappeared from the berried shrimp.
After 2-3 days, I began to spot tiny shrimplets on the glass.
Maybe it's too tiny for us to see, or its hiding in the substrate when it just born. Takes a couple of days before it swims around, probably.
from 14L to 8L tank.
I have ista glued a shrimp guard on the hob filter inflow. Had only 2 small 3cm SAEs and other shrimps in the tank. Would the berried shrimp have dropped its eggs in the first few days being introduced into the tank? Why now?
I see those sold in bags at c328, newborn shrimp are free swimming and very active there. My tank does not really offer many hiding spots.
Can shrimplets hatch even after the eggs were dropped by the mother shrimp?
Its possible... dropping of eggs can occur anytime, could be immediate or could also be after a few days, usually it's because the shrimp needs to molt due to change in tank environment, so it has to drop the undeveloped eggs before that process.
The SAE may also snack on some of the newborn shrimplets if they happen to catch them, so it's one of the factors too.
Like what 14litre mentioned, the newborn shrimps may just be hiding somewhere, they are so tiny they can even hide in between soil granules, so just wait a few days and see if any of the survivors manage to grow larger and become more visible. There is always another round for the shrimps to berry again and hatch new shrimplets anyways.
I have removed the SAEs, only otos and a yamato besides the red cherries. I have only one dark blue shrimp, possible for them to interbreed? Both blue and red shrimps look alike in terms of looks and body shapes. Same genus?
Thats tough to know for sure, it could be either neocaridina or caridina (both have similar looking variants in various shades of blue), you will need to check with the seller of that blue shrimp to find out. If in doubt and you don't want any interbreeding, then just separate the blue one to another tank.
Didnt know that, are red cherry shrimp of different variants too? I want interbreeding to occur, trying to get some purple shrimps
ya, especially those cherry or sakuras. I didnt even know a few is berried, then the shrimplets also camo-ed well on the substrate so cannot see until they are bigger. Feeding time will be a good way to check
Not really.
You can get (or diy) those egg hatching "device" (or container). Basically it's to keep the eggs in circulation (using air bubbles from the airpump).
Some people did this when the berried shrimp died. They will extract the eggs carefully and put it into this hatcher.
Give it a couple of days and see if the shrimplets comes out to the open.
I used to do the same.
Tried to find those bag with berried shrimps.
But i was not successful to see the population grow. In fact all died soon after.
That was quite sometime ago.
I learnt that it could be my tank condition is not stabilised or optimum for RCS to thrive.
Recently my RCS began to breed non stop. I didn't expected it because I bought it as the algae crew for my iwaguni setup.
Once the condition suits the shrimps, it will breed like crazy, just like how you read from other sources.
This is true once the condition is in their favor. But this symptom only appeared 1-2 months later after I introduced the shrimps into my tank.
I'm not saying your tank is not conditioned yet.
It takes a bit of time for the tank to stabilised as well as for the shrimps to adapt.
It's not the same as buying a pregnant guppy. Bring it home and soon you will see the babies.
Guppies are very hardy.
Shrimps are very sensitive, even for cherries.
For shrimps, we need to pay close attention to the water parameters and nature will take its course for the rest.
Lastly, keep trying and you will be there.
from 14L to 8L tank.
Well said 14litre ! Patient ! RCS will really breed non stop if the water condition is good.
Yeah, there are many color variants of neocaridina shrimps in the market, all selectively line bred to achieve specific colors and patterns.
Here are links to just some of the more common examples:

Well, interbreeding to get a certain color for neocaridinia shrimps isn't as simple as just a red shrimp and blue shrimp mating and then producing purple ones... it doesn't exactly work that way. Shrimps that we buy that have nice colors are specifically line bred over hundreds of generations to achieve those stable colors and patterns, so when you interbreed shrimps of different color together, the process will set about unravelling their genetic pool. So in this example, what you'll tend to get are different colors in the offspring, ie. some may be red, some may be blue (depending on which gene is more dominant in each shrimp), and their quality grading will also tend to vary and usually decrease due to the move away from the line breeding process.
That being said, if you are keen on finding new colors and patterns, what you will be looking for are odd color mutations that pop out once in a while (and this can happen even if you only breed one color, as they all possess the possibility of random color mutations too), like the 1 shrimp out of 1000 that happen to show a slight tint of purple, then try to find another one with that similar color and then start a line breeding program.
I guess so far no one has been able to breed out a stable line of purple shrimps yet (otherwise they would already be readily available at most LFS by now), so maybe if you are lucky and can work at line breeding though dozens of generations to get stable purple shrimps, it could happen.
