Was wondering if anyone may have any ideas on the mysterious illness that we
have been unable to solve in my boyfriends pond. I noticed that one of the
fish in the pond has something wrong with his eye. On closer inspection the
eye had gone white and had a fungus growing from it with a little white lump
just back from the eye. We treated the pond with an antifungal treatment
from tetrapond. It seemed to take the fungus off the eye but the white lump
behind the eye remained. Over the winter the fish has now developed dropsy
and has been removed from the pond. Only thing is one of the other fish has
now developed a white lump behind his eye, but the main eye seems ok. Any
ideas as to what it may be and what course of treatment to take.
Any help appreciated.
