How is your water parameter? How many Cherry you have? Maybe you can provide what is your setup detail. So we can help to advice you.
I have them for more than a month, they are growing bigger but doesn't breed.
Is there something they are lacking to breed?

Setup soil , moss and sponge filter in 1.5ft tank.
only 6 shrimps
Ph - 6.6
Ammonia - 0
Any of those shrimps are males? More specifically, adult male shrimps?
Saw some with yellowish patch on top , maybe saddle? And some no yellow patch
Those with the yellow patch inside their backs would be the saddled females, the visible saddle indicates they are ready to mate.Originally Posted by Cmlee
The ones without the saddle could be males (or could be juvenile females too). Look at the shape of their body, if they are already adult size (>2cm length) and look quite slim around the mid-section, good chance they are males.
If there are male shrimps in the tank, then its just a matter of time before they mate with the females (assuming the tank conditions are good, they have enough food to eat and are comfortable in the environment).
If they are going bigger I guess the conditions should be good for them to breed as well?
Yes as long as your ammonia, nitrite and nitrate are acceptable and you're not adding anything that kills shrimp (eg) copper they should start breedng soon just be patient!

I am not able to bring down my nitrate which is 40. How long does it take for them to breed nornally?
Although cherry shrimps can adapt to and tolerate those nitrate levels, it'll be better if you can still try to continue lowering it, every bit counts.
Usually when a female shrimp has mated and the visible eggs form up under its belly, it usually takes around 3-4 weeks (quicker if the water is warmer, slower if the water is cooler) before they hatch into baby shrimplets.
Tried all means to lower nitrate it doesn't help, I guess unless I use RO or distilled water that is too costly for me
Dont need to care too much about the parameters. Just ensure they are consistent and dont fluctuate. Be patient and you will see the berried female soon :-) my cherries breeding profusely in super hard water and high nitrates and high temp in window side tank without problem. Takes time for them to adapt. Good luck
Like what you mentioned to me a while back, you tested your source tap water and it already has high nitrate levels (> 40ppm), so even with lots of water changes with that tap water, the nitrates will tend to have difficulty going lower than what your tap water already contains... in some cases even if the tank nitrates do manage to get reduced, the water changes with that high nitrate tap water may actually raise the nitrates back up again. So its like fighting an uphill battle.
So if you want to reduce nitrates, then have to use a water source with less nitrates to change water (ie. cleaner tap water or distilled water) or add even more fast growing plants to soak up more of the nitrates at a quicker rate, along with reducing bio-load and feeding to slow down the overall rate of nitrate production.
