Hello, I'm new to this forum, glad to be here.

[Christopher Howard]

I've had a koi pond for a couple of years now. The other day I noticed two of the fish were scraping on the bottom of the pond, a sign I've always taken as an indication of a parasite infestation. However, the water temp is just above freezing, and I have an 11watt UV lamp in my filter. The water is clear and is a quarter decanted every month. I have just bought some anti-parasite treatment (not used yet) but my local aquarist tells me that the treatment is ineffective at low temperatures and that parasites are unlikely in such cold water. Does anyone have any experience with pond parasites? Any advice would be gratefully received, thank you. (I have included a picture of the tail of one of my koi with what appear to be white spots.)

Welcome and outside temps are not what to think about ,you need water temps .Do you have a liquid test kit

Welcome The white bumps on the tail appear to be koi / carp pox, which is a virus.

Welcome to our forum. I don't have koi, but there are a lot here that keep them. They will help you.

That does look like koi pox - @Dave 54 will pop in here and confirm. If that's the case, no treatment is necessary - it's not deadly, just unsightly.

Welcome. If it is koi pox it will go away as the water temps go up on its own.

I hear you are getting a very cold winter blast so try to stay warm and stock up on food if needed.
