For smaller tanks, dosing polyplab medic(hydrogen peroxide) according to the instructions will help with managing ich. it won’t eradicate the parasite or ‘cure’ your fish but it’ll keep the parasite population down. Feeding your fish well, keeping their stress down(by not introducing too many at once, or too many fish for tank size for e.g) and boosting their immune system with the right foods will also help them fight parasites and diseases better.
