My biggest male, 6inch blue snake skin, stopped eating a week ago and just sits in the corner. two weeks before that, he and three of my other discus had a internal. Made a huge mistake and feed live black worms, never again. I quarantined them with polyguard, got them eating and after a week or so put then back up in the main tank. Once they were back up He stopped eating. However, one of the little discus ended up with the internal again, shes back in the qt tank. I don't think the male has a internal bc hes not pooping white.
