I thought my Catfish would take it like a G, too, but they just died last. All I got is 7 common goldfish, 1 pleco, and 1 Betta and my goldfish stayed alive through the whole thing without even showing a symptom, the ich isn't effecting them one bit!!
So I just feed them garlic extract directly or make a sprinkle it on their food or what? What a about minced garlic? And whats a uv sterilizer? Never heard of it. I got nothing to lose because the goldfish are invincible, I think that the pleco has it, and I know the Betta has it. I could just put the Betta in a bowl that I have if the treatment is too risky. But I do got my plants to worry about. I don't want to lose those, but I also don't want this ich no more. And whats the procedure on bleaching? Thanks a lot.
