your basically gonna deal with shusui for that baby blue. the good news is they rapidly grow out of it and turn white.
I love blue, not a doutsu fan and rely on asagi to get me my blue. there are different grades of blue in asagi and thier color tends to be more permanent than Shusui. The blue i like is narumi, and even lighter is reverse. Breeders who breed these two include Hosokai and Otsuka. Look into them and see, I think you'd be happier with Wagoi to satify her craving for baby blue.....
