Now here are 3 main questions.
1. Can I keep a shoal of 5-6 Peppered Corydoras in my tank?
2. If possible, any tips for keeping and breeding?
3. Any other recommended corydoras(I was thinking pygmies or dwarves, but wanted to try a larger cory this time, and my LFS moved, so, no more local Pygmies and Dwarves

My criterias are: Not disturbing shrimps Not hunting shrimplets. Not disturbing plants(not too much anyways)
Any comments, replies, messages or/and tips are appreciated!!!
