Help rapid breathing

[danny zubot]

For the past month my female ocelaris clown been breathing rapidly, has become lathargic and I haven't seen her eat in weeks. Her male and all other fish are fine. This was going on well before my NH4 spike and I'm suprised that she made it through the whole thing. I have also noticed in the past couple of days some decay of her recently inflamed gills, but I haven't noticed any parasites. In most cases like this a fish would have either died or recovered by now and I really hate seeing her suffer. Can anyone recommend a possible treatment. If I have to quarentine her will I need to put the male in with her? I haven't ruled out old age because she looks it, (Alan?) with wrinkles and all.

Thanks!

Don't know the age, Danny - came to me from Josh originally. Could be an age thing, but there's obviously something else going on, by the sounds of it.
