Looking very good Orlando. I don't recall, but I suspect you have bred kohaku and sanke in previous years. Have yours developed to a deep red in the past, or do they just get red-orange? Is the deep red tricky to get, or do deep red oyagoi just tend to produce deep red young (once they mature).
I once did a kohaku/sanke spawn long ago, before the efforts of recent years, most of the resulting kohaku and sanke were orange at a year old, even though the oyagoi were all a deep red. But there was one tancho sanke though whose head spot was pretty red.
