Cannot Cure My Discus... HELP!?!?

They didn't make it. They started getting blisters and red lines throughout their bodies. Signs of organ failure. I was suspecting they were born this way, but I was hoping that I could nurse them back to good health. I did my best.

Aww, sorry to hear that. At least you tried, that's what matters.

For future reference, it is recommended to have a quarantine tank for all new fish. This will prevent disease spread to your old fish, if the new ones come in with any disease. It is especially crucial if you know they are already sick.
