Hi as previously said almost a leather carp. I would add that itsa cross between a carp and a koi to give that silver rather than A bronze colour. A pool I fish contains these crosses in both common and mirror varieties. And look almost identical.
I believe that there is some difference in ideas as to what constitutes a ghost carp. When I first encountered fish so called they were silver but had a white line down there backs. When the cruised near the surface all you could see was a white line travelling thru the water. Since then I have seen this silver type described thus. Any way still a damn fine fish. John
