My tank is doing well, and no other fish have been affected, but one day about a month ago, this white line showed up on my Tomini Tang. He is still still doing well, but this has been on his left side for several weeks now. It appears to be getting better. Looks as if he rubbed up against a rock or something. I have done some searching on google for fish diseases, but I'm not sure if this is a disease, or just an injury. I was hoping somebody here could shed some light. Here is the best pic I could get. Moving fish are hard to get a close-up pic!
Thanks for any help or suggestions.
