Howdy. I have two new babies, a lionhead and a pom pom. I have had them for 6 days in qt.This morning the lionhead had a fungus looking spot on his back and a pinkish spot on his head. I added a little melafix and I am in the process of bring up the salt to .33 . After about 3 hours I cannot see the rather large looking spot on his back. The pink one on his head is still there. Is this over production of mucous? I will keep an eye on him. I will always attempt to treat naturally if possible. However I was forced to look at the meds that I do have, that I never use. So my question is...has anyone used API fungus cure as a swab on treatment? If so where the results positive? I am not considering using it at this time. I think clean water ,salt and the natural antifungal of the Melaleuca should suffice for now. I also have metro meds food. It is over a year old though. Always in an airtight container. Still good? Thanks in advance.
