You need to get your water tested.
Take as sample of water to the lfs and ask them to write the readings down for you.
The fish might of been pecking at his dead body.
Fungus can grow on dead tissue.
Did the fish have a white or red spot that turned into a hole.

no not as far as im aware, literally i came back from the shop and the fish was dead with the hole in its side, iv heard of cotton wool disease but not green??

Going to get a link to hole in the side just for you to take a look at.

Clinical signs

Fish fungus appears as grey/white patches on the skin or gills that resemble tufts of cotton-wool. At a later stage they may become brown or green as they trap sediment or algae. If the fish is removed from the water, the fungus appears as a slimy matted mass. Saprolegnia normally establishes as small, focal infections that then spread rapidly over the body or gills. As it spreads, healthy tissue is destroyed. There is often little inflammation unless there is an underlying bacterial infection. Microscopic examination shows broad, non-septate (no dividing cell walls) hyphae of varying diameters.

If it was';t hole in the side the the fish could of been pecking at the dead body.

this happened to one of my fish before when i found it laying in the bottom of the tank with a hole in its side its probably due to other fish pecking at the dead fish and the fish starts to rot causing the green fungus. i worked at a fish store and found this quite frequently.
