Do you know what this is?
It looks like screatches (against the gravel?) rather than a parasite...the fins are totally clean, so it is not ich, but could it be something related?
(the fish was moved recently, at least twice, the "scratches" appeared within the last two days; other khulis in the tank don't seem to have this problem at all)

Thank you very much for any info.
