Also known as Fish Pox. Most koi carry this gene, the herpes
virus - not to be mix up with the virus that causes K.H.V. or
There is a lot written about this complaint, and most of it is
rubbish. It mainly shows itself on the fish's fins as a white blob, which
resembles soft whitish candle wax, very smooth to the touch.

Sometimes it's around the head region.
Most fish override this problem

If you try to remove it, which some idiots do as they

There is a third form of the disease which shows its self as a thin
membrane over the scales and sometimes around the mouth area. It's the same
colour as the spots but more translucent and looks like a smear of white jelly.

the fish is when it's diagnosed as white spot and formalin and malacite green
is poured into the pond. Then the fish die from toxemia not fish or carp pox.
Do not confuse these breeding tubercles with fish pox, which is always
on main pectoral fin rays and as white spots on gill covers.
