medicine question x-posted

Hi all,

I bought a used tank about a week ago which contains an oscar fish, with
what I believe is hole in the head disease. I purchased some medicine
called Hole in the Head Guard and was wondering if anyone has experience
with this medicine or not. Does it work? It looks like a complicated
procedure for using it, and I only have a few days experience with oscars,
but I have already fallen in love with this fish. I would hate it if he
died. do they die from hole in the head disease? Thanks and any help would
be greatly appreciated.

Sarah
