I have a 2.5 gal. with one female betta and one ADF. I believe the Betta has ich. She has a white patch on her side. I started using a medication and doing 25% water changes this week. The temp is 82F. I thought I read somewhere that ADF's can't get ich. Anyone know for sure? Also, are there any ich meds to avoid with my ADF? How long do I continue the treatment and how will I know when the parasites/cysts are all gone? thanks
