i would get rid of the gravel and have coral sand only,
it will make cleaning a whole lot easier. i have coral sand and no it does not cause gill irritations in fact mbuna love to sift, spit and dig pits in it.
the scratching is called flashing and they will do this from time to time on occasions after water changes or sudden changes in water parameters....however................
if they are doing a lot of it, like several times a minute (each) perhaps there could be another problem called ich.
this can be seen on fish as little grains like salt and can be remedied by checking out the library section i think it's under illness.
hope this helps
