Towards a new strain of tosakin?

First let me update the offspring of Mr. DBS line in my place. Since it has become the basic ingredient for my tosakin project, I see the need to preserve it. Here are two very different siblings from this line:

My purpose in this tosakin project is to create tosakin with deep red color. I have posted this in the diary #11 this year. From my crossing to get a deep red color, I get two surprises which I have not posted before.

The first one is a red-white fish with a better red color (though not so intense yet) which has a tail shape closer to a decent tosakin (with a shorter tail). But I do think this fish is the key that will bring me one step closer to my goal. That is why I named her the Key. She looks like this:

In the pond, the red color is a bit more intense than this picture. Somehow, I cannot get the color right during my photo session. But the color difference is visible when she is paired with the DBS line as shown below:

I do think that the cross between the DBS line (male) and the Key (female) will produce a decent tosakin with better coloration. So, I mated the Key with several male from DBS line. These are the male fishes:

The one on the right is not the DBS line. He is the deep red semi tosakin fish. I mated him with the Key to preserve the intense red color to be used for the next step of the project. I cannot wait to see the result!

The second surprise is the appearance of a different kind of tosakin. The characterstics are a softer tail, but longer. And a better red color than the DBS line. I do not recall what crossing that produces them. I suspect the butterfly is responsible for this. There are two of them, both are male:

The first fish:

The second fish:

Aren’t they beautiful?

Well, can we call them tosakin? Perhaps not. Not in the standard sense. But, can we create a different strain of tosakin? A softer and longer type of tail. Or is it a sin? Frankly, my mind runs wild imagining a possibility to put my signature on a new strain of tosakin!

But I do not have female fish with their characteristics.

What I will do for sure is to cross them with the female tosakin from the DBS line above:

And what will the result be? I can only imagine something good and beautiful! 😊
