Ok, after an operation that really wasnt that hard I caught the two. I was supposed to get them to the store to show so I can get the correct medication, but it was closed. Then I noticed that when in transpot bag the colours dissapear and you hardly notice the patches so I think they had it at arrival. I got one sort of medicine, sera costapur. The symptons and how it looks matched that medicine, but don´t want to use it until Im sure. So i got better pics.
As you can see the white is gone and now it looks like the skin has only been rubbed of. But the hillies are now in an own tank.
