Hi pythoren and welcome to the forum. It's possible that your cories have developed a bacterial infection called columnaris. For treatment, I'd suggest removing the two cories and putting them in a hospital tank where you can treat with API Furan-2 or Jungle Labs Fungus Cure. You may want to start the meds at half dose as cories can sometimes be sensitive to medications.

I had to columnaris in my tank and if that's the case you need to move quickly. My guppies all died before any of them showed any symptoms. I also highly recommend you uv filters because that has prevented any new outbreaks. I used fungus cure but they all died before I could finish the first treatment. It caused the water to turn dark color and you have to remove everything as it might stain it and it will destroy the bacteria in your filter.
