A few of my mollies seem to be showing signs of whitespot other fish seem ok at the moment. I have a whitespot treatment made by king british would it be ok to use this in my tank as i have an adf , cories and a couple of bn plecs. Should i transfer the ill mollies in to a 10 litre bucket with an airstone and treat them in there. Or should i treat the whole tank . Please help me i dont want to loose any of my fishes.
