fish scrape for many reasons, not just because they are sick... sometimes
ammonia can do it, pH being too acidic can cause this, and nitrite is said
to have an irritating feeling....
Before I treat (especially when no signs of illness are VISIBLE) a large
water change can fix all the out of balance water parameters, then if I
notice a problem, treat with the appropriate meds... but meds are a LAST
RESORT!!! I only treat meds when I see whitespot, mouth fungus, fin rot, or
something I can see.... flashing/scraping can be from bad water
conditions.... my advice would be to do a 25-50% water change, and watch
them carefully for a day... if they get better, you got lazy with your water
changes and the water quality was getting poorer as the days went by.....
Good luck..
