This morning I found three of my large fish dead in the pond. 1 goldfish (my biggest) and 2 shubunkins. Last week I also lost a couple of fish. This is the first time that this has happened to me since I introduced fish into the ponds over 6 years ago. Usually they come through winter okay. I just wondered if there was anything I could do to help any other fish. The goldfish and one of the shubunkins looked fine. No external injuries etc that I could see. On the other shubunkins face there were tiny white spots.Just like fullstops (they look like what we mothers used to call milkspots on our newborn babies.) Has anyone got an idea about this and is there anything I can do?
The goldfish I can say might not have gone through the winter because he did seem under the weather last autumn, having some white waxy spots on his sides. I couldn't see any sign of them now though, like I say he looked fine. I just wondered if it was worth dosing the pond with some eradik or something. I didn't know if it will work well in such cold weather.
