Bought her at Petco because I thought she was berried. Have her alone in a tub until I know for sure. It’s been 2 days and she’s still green

internet says 30-40 days, maybe i’m just being impatient
but I’d also like some advice on raising baby neo shrimp, what has worked for you guys? I want an army

I need to know all the little and big details as I’ve never owned shrimp before!
Here are a bunch of my questions:

What fish can go with them?
What aquatic plants should I buy? Preferably plants that can live on rocks, driftwood or on top of the tank!
What food do they eat?
Do aquatic plants rot easily?
How often do I need to clean the tank?
Should I buy sand or gravel?
Do shrimp and plants need lots of light or can it be moderate?
Should I get snails?
Most importantly, how long should I let the tank cycle for?
And finally, how much shrimp should I start with?

Thank you so much in advance!
