I would trust Kodama far more than myself! LOL They have many years of doing this, Myself I still consider slightly above novice. LOL The pecs of a male are usually more pointed on males than females. Also if you look at the dorsal fin usually females will spread outward in that region. Males tend to have smotther line in parallel with the dorsal. If it is a female, It's probably already spawned for the year and been fed lightly the last few weeks getting it ready to put up for auction and prepare for shipping. I agree Matt, I like the fine details of this fish far better than the Sanke. The sumi on this fish looks cleaner and IMO appears to be more stable as well, Yes it's going to develope a more finished look as it grows. I think it still has plenty of room to improve as it grows. The two of them should both make really nice breeders, Good bloodlines and genes to start working with!
Care to critique my three Kodama Koi? The Kikusui is from Aokiya, the showa, has a lot of room for development, It's a Suzujyu Koi, Female, and then the Beni Kumonryu is a Yamasan Koi and a male. Also Will have Shamu my female Kumonryu, Sunshine, My Ki Kin Doitsu, Thinking on working on a project with scaless koi.
Oh and BTW, My fish arrived three in the box and were doing wonderful when they arrived. absolutly stunning and healthy. Didn't seem the least bit stressed. I have them in QT right now. They did take about three days before they started feeding and even today only eat a small amount compred to all my other fish.
