I read this on TM forum and thought I'd ask here for them:
"fish disease - hole in the head
I have tried treating it with melafix 6 or 7 times now and the holes are getting larger. Is there anyone out there who has successfully treated it. She is my clown loach and she is very old, as I have had her 22 years, and is about one foot long. She is still very happy and lively, but I have been trying to combat this since end of last year, and these last few weeks I have noticed a progression in the disease, even with the use of melafix. I wouuld appreciate any input at all. Thank you."
