Hey all, had no problems with hole in the head since i was young with oscars and poor water quality which i always assumed was the cause... well my water is always pristine now and tested regularly 25% water change weekly or a 50% fortnightly if im busy!??? well a few weeks ago i added a large flowerhorn with some minor hith lesions now my festae have some small ones too and my prized midas has some supect marks too!!!! just dosed the tank with water lifes octozin ( active ingredient dimetridazole) hoping this clears it up quickly as some people claim.... always seems to be going so well then one dodgy fish uuuuurgh...
i'll post the results in due course, been some promising results on the oscar forums time will tell i guess...
