| Not an unusual occurrence at all Mitch. Many yamabuki get red spots as they age and often even shiro utsuri will show an orange stain ( a showa trait bleeding through) with age and development. One theory, and not one I necessarily agree with, says that a reaction to a harsh environment brings out natural 'camoulage' in koi and that things like latent color and shimmies emerge rather than the normal colors that a wild carp would produce. ??
