Tank size: Currently 28 litre hospital tank, normally 65 litre.
pH: 7.8
ammonia: 0
nitrite: 0
nitrate: 10
kH: 120-130
gH: 280 (very hard)
tank temp: 27C
Fish Symptoms (include full description including lesion, color, location, fish behavior):
Started with what looked like hole-in-the-head. Little craters all over his head and some dorsal fin erosion. Craters seem to be improving (or at least not developing anymore) but he's developed a pink spot on his side that looks like a pin-prick and now has a bumpy growth above one eye. The eye itself seems OK, not cloudy or bloody, but the lump is sitting on the top of it. Krib more sedate than usual and tends to hover at the back of the tank. Doesn't seem too interested in food but fins are spread (not clamped) and he moves alertly when disturbed. The eye doesn't pop out or seem swollen.
Volume and Frequency of water changes:
50% every two weeks in the main tank, whatever is needed to keep the hospital tank ammonia free (currently running chemical filtration that seems to be doing the trick but carefuly monitored).
Chemical Additives or Media in your tank:
No chemical media in main tank, where symptons developed. Only additives are quality water conditioner. He has been given a course of Furanol II in the hospital tank, as the symptoms were initially bacterial. This has ended and he's been in pristine, un-medicated water with just a little aquarium salt since. Baffled now and not sure how to proceed.
Tank inhabitants:
Main tank has a juvenile L-number plec (4-5 inches), a golden panchax (4 inches), a lonely male swordtail and two bumblebee cats (4 inches). No shoaling fish and all the fish are active and don't spend much time hiding (apart from the cats, who are nocturnal). All get on, no fighting except for occasional some squabbles over food and none of them are wary or behave stressed.
Recent additions to your tank (living or decoration):
Changed decor from live to silk plants several weeks ago but all other decor has been in there for months and months. Silk plants were not new and had been used in other tanks, but very well cleaned and dried before use in this tank.
Exposure to chemicals:
Unknown but highly unlikely. We're very careful.

UPDATE:
The area around the affected eye seems to have some yellowy-orange colouration and the eye seems to be starting to pop out a bit. The growth is also getting bigger. He's developed a white spot about half-way down his back, at the base of his dorsal, and there is a patch of lighter fin just above it that is new.
