My moor has a single small white dot on the edge of his tail fin - about
the
size of a pin head. Its not gone any bigger and the others don't seem to
have anything and all seem to be healthy so far.

Very interesting. My blue "ryukin," whom I suspect has more than a
little Moor in her, gets exactly the same thing from time to time. It
always is in the same place, the top edge of tail fin, and always goes
completely away after a couple of days. I was worried about ich at
first, but now i dont' think that's it.
