Hello! I'm new to the forums and joined to be able to get advice and give advice. I have a problem with one of my koi. He/she has what I believe to be an ulcer on its side. I need advice on treatment. The fish is quarantined now and I plan on starting treatment today. I will try to post a pic. Any advice will be greatly appreciated. Thanks!
