Hi hollowman

thank you for sharing your experience and yes having a fluke free display tank is everyone's dream I think. =) so for now I'm after a more cost effective way to treat 6ft tank and hopefully it doesn't take too much effort either then we could just repeat every 6month to keep the number down, but if using above treatment protocol as described by sayid would get rid of it then I would like to give that a try so let's hope sayid is still around to tell us the outcome.
and yes I think you are right, those fussy eater will no doubt spit the medicated food out.

btw I just found something called kusuri wormer plus which looks like a pretty cost effective product to control fluke and it sounds pretty safe for display tank. just wondering if we can still source this in australia?

Regards
George
