Not to nit pick...well OK exactly to nit pick...the OP never mentioned
anything about threads or mouth damage, aside fromt the one fish that had
it's "face eaten off". Would it not make more sense to take a dead fish to
the vet and get it tested before you begin dosing for a disease that you are
not sure of?

I'd rather treat it and not loose another fish than wait. The vet isn't
really well up on fish and is looking into what antibiotics they can
recommend. We are really restricted on what we can use here. The fact
that it gets worse when the water temperature falls makes me inclined
to think that it is columnaris and that it's now internal due to the
faeces being white.

The fish with it's face eaten away was fine the night before but
floating dead the next morning. Being in the UK we don't have a lot of
predators, apart from the herons and the pond is netted against them.

I've been posting questions about this on and off since November but
didn't realise my news server was set to keep posts for this group
local so I saw my post but it wasn't sent to the world. I only realised
when a web based news reader I'm testing didn't show the post, so I
have been trying to get help but just thought no one had any
suggestions.
