Welcome to AC! You might get a better response in the angel/discus cichlid forum.
Both fish look to me to have frayed fins...what are your water parameters; ammonia, nitrite & nitrate? How often do you change water & how much each time? What foods do you feed & how often? What size tank? Any other fish? How long have you had them?
We need a lot of info, help us to help your fish. They look to need some help, what size are they? Tell us everything...& then we'll ask some more.
When any problems arise in my tanks my first answer is to change water, a lot & often.
