I have a sick fish that I am unsure of it's problem. Attached is a photo. It is almost like a flesh wound across his 'forehead'. Just noticed it today, and added a dose of Melafix to the tank, but want to make sure I am on the right path. Thanks!
Post this over in the disease forum, you will probably get more of a response. Also there is a post in the top by Beth that shows pictures of diseases on fish, you may find out what it is and the treatment it needs, hope that helps. Happy Tanking
