1 of my platys has a patch on 1 side where his scales have been discoloured and seem to be deteriorating. None of his fins have any white stuff on them so dont think its fin rot/fungus. in the last hour or so he's been very lathargic and almost rolling around on the bottom.
Any ideas wat he's got? Also should I take him out of the main tank to avoid infecting the others?
