I got an Oscar with HITH off of CL and treating it with Microbe-Lift Artemiss and I also use Herbtana for ICK. I've used the Artemiss on fish who's tails were mostly chomped off and it grew back within days. My new ClownKnife was beaten up pretty badly by one of my oscars and after adding the Artemiss within a couple of days all healed up. Now with the Oscar HITH, within only a couple of days the scars are healing up nicely. Not sure what's in it but the stuff is magic for healing up fish fast. I"ve never had to do the full 10 day treatment. You can only get it online, entirelypets.com is a good one they have it.
