I'm not sure if it's a disease or not can't tell that's why I'm posting with pictures. I got a new smaller discus and those two have been kind of fighting/bickering with each other so maybe just a wound but here we go. Please tell me what you think. Thought maybe ich but I'm not sure.

Did you quarantine the new addition? Do you have a Quarantine tank that you can use for your affected fish?

I think you should fill out the questionarie in the emergency room
