Scratching certainly indicates stress and not necessarily a disease. But in case of Oodinium, it is usually the first symptom to be observed, long before you see any sign of that fine “white powder” on the fish’s skin.
I am not surprised that you did not find the medicine I mentioned. In Germany, it is very difficult to buy it. But there are some brands of fish-medicine which consist of that stuff entirely. One is “Hexa-Ex” by TETRA, another “Spirohexol” by JBL. In the description Oodinium is not mentioned at all, but we Parosphromenus-friends have a lot of experience with it as the best means against that disease.
