hey mate, congrats :clap: i feed my corys on wafer things, with bloodworm once a week (this helps spawning). My pandas normally spawn when they are just generally frisky :lol: but a cool water change is the classic trick (which works wonders!)
my corys lay on my huge onion plant. more males than females is the best ratio, and lots of space is good. Be careful not to cover the tank too much, my poor female sometimes crashes into things escaping the males
any questions ask
goodluck mate
