I am treating them with Seachem Cupramine for 3 days now. Initially I'm thinking it was either Ich or Velvet that's why I use a copper sulfate medication. I'm doing a daily 50% WC to keep up with the water parameters, the temperature is at 88°F. They are swimming alright but not eating. Here are some pictures.
Hoping for your inputs.
