Hi and welcome to the forum

Most shrimp will breed when they are mature, well fed and kept in good water.

If you are doing regular water changes that should help encourage them.

It appears you have a carbon dioxide (CO2) diffuser in the tank. If you are adding CO2, make sure the pH isn't dropping too much because that will stop them breeding.

Feed them 3-5 times per day.

When the weather cools down, they should breed.

-------------------------
To help keep the tank water temperature cooler, turn off electrical appliances in the room.
Have a fan blowing air over the tank.
Turn the aquarium light off during the middle of the day when it's really hot.
If you have a lid on the tank, remove it to allow heat out.

Most fish and shrimp will be fine up to 30C for a few months over summer, (32C being the top temperature for many fish species).

Increase aeration/ surface turbulence in hot weather to maximise the oxygen in the water. The warmer the water, the less oxygen it holds and low oxygen levels can stop shrimp breeding.

With a planted tank that gets CO2, increasing aeration will push the CO2 out of the water, so it's a compromise. Personally, I would turn off CO2 when the water temperature is above 28C so there is less chance of the fish/ shrimp suffocating.

thanks for your lovely reply.

I will take care of that.....however do shrimps jump from the aquarium i just want to now as if i will remove the lid of my aquarium will they try to come out just to know about?

Some shrimp do jump but it's usually at night or if something is chasing them. If you reduce the water level a couple of inches, it should prevent them jumping out of the tank, assuming they try to.
