As long as your water parameters are in an acceptable range for guppies, the
guppies were healthy at the time of purchase, you have had them for a month
or two, and there are no other signs, your guppies should be fine. We all
get itches that need to be scratched. As always, do watch them for any
deterioration in their health such as increased scratching and/or shimmying.

I have about 13 guppies and I noticed that ocassionally they like
scratching themselves on the gravel. There is no evidence of Ick or any
other disease. Is this normal for them to just scrach against the gravel?
They don't do it often.
