I have just moved house and moved17 koi to my new pond and in doing so I noticed that one of them has what appears to be a wart or boil. (See photos) I have kept it in isolation (very topical) until air can find out what it is, whether it is s threat to the other koi and how to treat it. Can anyone help please?
