peppered corys questions

[KittenFishMom]

Question #1: My peppered corys have gotten much darker after I moved them from a tank with light substrate to a tank with black sand on the bottom. I'm guessing it is to help them blend in with their environment. Is this normal or is something else going on?

Question #2: Will my peppered corys eat scuds? I have been working on a colony of scuds, but am not sure if the peppered corys mouths are big enough to eat the large scuds I have. My yoyo loaches loved scuds, but I rehomed the yoyo loaches because I wanted them in a bigger group. Without the yoyo loaches, I'm not sure I have fish that will eat enough scuds to make keeping a colony make sense. I currently have 1 male plakat betta, neon tetras, kuhli loaches, peppered corys and some female flagfish.

Very normal.  Also a good sign they like the surroundings.
