Check out aquarium Coop recommended quarantine method. Just search it on YouTube, it is the method I use and it is great, I was killing fish over and over until I started using their quarantine method.
Also I keep guppies and still use some flake food, but I always pre soak it in tank water and let it expand before feeding it. It solved my bloat issues. Honestly I mix the food up, and their favorite is the tropical bug bites for small fish. My cories really like the Hikari sinking pellets.
