It is called cross - contamination meaning different discus groups infect each other with different types of pathogens .
Do big daily water changes with aged water to strip as much pathogens from the water as you can for now and just observe them closely . They might get better on them selfs in a couple of days or you might need to medicate and help them overcome this .It all depends of how the things will progress. Watch for symptoms on their skin and their feces for now .
Good luck Mescach .
