It might be worth waiting for a few more weeks before getting shrimp. They graze constantly on biofilm and algae in the tank, stuff that's grown on the tank walls and plants, and they're also sensitive to changes in water parameters, so a stable tank is important.
I had to move my red cherry colony to a newly set up, clean tank recently and they did survive it, but had to be very on top of testing and water changes while the tank was getting established, and I needed to feed the shrimp extras like Shrimp Cuisine, snowflake food and things like that daily, since there wasn't any biofilm or soft algae for them to graze on yet. Mine made it, but they'd also been bred in my tank water, so it was probably less stressful for them that it might be for ones you've just bought in, who already have a lot of adjusting to do. I'd say it took a month for the tank to develop a decent amount of biofilm for them to be able to graze all day and not rely on the extra feedings completely. (they still get extra feedings 2-3 times a week, they're just not dependent on it anymore).
Oh! Also recommend things like almond leaves and cholla wood, shrimp love grazing on those.
Don't panic if it takes a while before you see breeding activity. I added shrimp a couple of times, and it still took a good six months before I finally had baby shrimp. Then the population just exploded. But my tank also had fish, so that might have slowed things down. Looks like a lovely set up for shrimp
