Ok, today I was watching my fish scratching their heads and body on the gravel and the caves. My convict cichlids look fine. but, my bumblebee cichlid,ice blue zebra cichlid, was scratching everything for a minute then rest's for a minute then he scratches again. what is the easiest way to cure it?? please help. I dont want to loose my "wild type" zebra cichlid, or my bumblebee...
