I noticed today one of my neons has a white cotton wool like growth on its mouth and I assume it's mouth fungus. I have read the best treatment is kanamycin based treatments. However when I checked with my local shop I was told it can't be sold in the UK without a vets prescription. I have ordered API pimafix from Amazon on next day delivery which I have heard is good. Can anyone recommend any other treatments that can be bought in the UK. There isn't a vet within the area that can do fish and it's a lot of money to spend on a tetra to go to one.
