The Diary of a Goldfish Breeder 2021, tosakin

The Diary of a Goldfish Breeder 2021 (5)

Date: March 9, 2021

               I try to take better pictures of my tosakin this morning. I realize that it is a bit hard to get a clear view of red-white tosakin in a white bowl. I wish I had a black one. Anyway, enjoy the pics.

This is the only productive female tosakin I have right now. She is an offspring of my Nagoya tosakin and my own tosakin line. She has a defect on the dorsal fin, namely, the dorsal fin does not cover the whole backbone.
This is the male tosakin I paired with the red-white female above. He is also a young tosakin.
These are the offspring of the two above, approximately three weeks old. They were many, but I culled out a lot since the flatness of the middle tail (as seen from side-view is not desirable. The angle of the tail is too upward. I also expect that some of the offspring will become all white since both parents are dominantly white. This is a feature I want to correct in the other pairing.
This is the original tosakin I bought from Nagoya, Japan. The growth in the head is a sign of his old age (more than two years old). He is the uncle of the two red-white tosakin above.
This is the offspring of the Nagoya tosakin and the redwhite female. So, this is a marriage between uncle and niece. The angle of the middle tail (as seen from side-view) looks better. And to me, they look more uniform. Promising. I think if I still have the chance, this is the pair I need to breed again.
This is a male grey tosakin, as a sibling to the two red-white tosakin above. My own previous tosakin line (as one of the ancestor of the two red-white and this grey) was a grey thailand tosakin, so it is not surprising to get grey fishes in the descendants. I mated this grey with the red-white female also. i cannot produce the picture of the offspring since they are still very small (less than two weeks old).
This is my male improved flysakin (a cross between tosakin and butterfly) that has been crossed back to tosakin. The flips are definitely tosakin. The thousand rays in the tail are also the trait of tosakin. But the middle tail is still split, and the whole tail looks soft (feasible only when they are swimming). I also pair this with the female red-white tosakin in the hope to create a tosakin with longer tail as my line’s uniqueness.
These are the two fishes with intense red coloration that I would like to be the characteristic of my tosakin line also. My friend and me call these two the two Beni, since Beni is a koi terminology to refer to the deep red coloration (if I am not mistaken). I already have the offspring of these two Beni with my red-white female tosakin. It will still be a long process to create a true tosakin from this cross.
These two are fertile female improved flysakin. The tail characteristics vary from soft to hard, from medium size to long. Yet, we can see a resemblance of tosakin in them. I mated these two with the original Nagoya.
