Thanks for your reply, Luke. I meant this as a thread to study the development of 2 koi from the same spawn. Perhaps Maruyamas are not common/popular in the US, therefore not much interest?
One thing I note about Maruyama kohakus, they have a tendency to develop shimmies. 2 out of my 4 Maruyama kohakus have got shimmies. Well, one each. If you look carefully, F2 has a tiny one near the dorsal fin. Friends with Maruyama kohakus have made the same observation on their fish.
Cheers,
Paul
