Chris,

Any chance you could post a photo of the fish somewhere - would make it
a lot easier for others to help with the diagnosis. If you don't have
a place, and want me to put it on my web site, post here and send me an
email (I don't check this email account often, so post here so I know
to look at the picture) and I'll put it up on my web site for a while.
