Breeding tiger shrimp

A fellow hobbyist just gave me 4 tiger shrimp. Their might be a 5th, unsure. And a ton of guppy grass for free. I put them in a 10g with a divider. The tank has an injured cichlid on 1 side and the shrimps on the other. Fyi the shrimps CANNOT go through the divider. I guarantee you they are safe. It is impenetrable. So I was wondering what my chances of breeding them are? Are they easy like cherries? Even if I don't have both sexes that's not a major concern, I don't mind buying 1 or 2 more. Advice?

This is my first shrimps I have ever owned. Are they easy to breed?

I'd really like to know if its possible. My water is soft and the ph is 6.4 in the tank. Btw, the divider has holes about 5 picometers long. just to give you an example, 1 picometer is invisible to the naked eye. And the shrimps still havent escaped 1 day later so I know their ok.
