| I’ve not been breeding gosanke long enough to answer the question, I can only put my ‘take’ on it. Over the years I have bought many kohaku from all sorts of breeders, Having kept these koi in my ponds and those of friends I have seen koi from some breeders never lose their beni, yet those from other breeders often loosing their beni all too frequently. So genetics must be in there somewhere with this problem. This year I have a large list of gosanke I plan on breeding so it may help me figure out a little more. But last year I spawned 2 kohaku females, from one spawn there were many shiromuji at first cull, about half of the non-patterned koi were white, the others red. From the other spawning hardly any of the fry were white, most were red. As the year went by constantly koi would turn muji in the pond where many white fry were found early on, this did not happen in the other spawning and very few shiromuji koi have been found. This may all be a coincidence, but they were all bred with same water supply which was very hard (no RO). There have been hiccups with these koi during this winter, they have all been treated for some kind of parasite. Although the parasites were different, both spawnings have had trauma to go though, these koi have followed the same trend one type a few have lost their beni, the others have not. As has been said many times, the type of red makes a difference, the spawning which were most prone to losing their beni are a much deeper red, the spawning with the very stable beni are more ‘orange’ But it is also possible to tell the ones which may lose their colour and the ones which won’t. It can be seen in the thickness of the colour. At present, I can’t see that the water type has much to do with it, but I could be wrong? For me at this stage, it leave more questions than answers.
