Flysakin is a term my friend (mr. Harlim) gave to my Tosakin – Butterfly cross. At first, I objected. I would like to give a more creative name. But I could not come up with one. So, since this variety was just a transition fish to reject, I did not think I need to put effort in thinking about a more proper name. This name was used since.

It is a transition fish. Tosakin was (and is) rare in Indonesia. When I imported some from Japan, I had limited success in breeding them. Most of the offspring had partial or no dorsal fins. That was a disaster. My guess, the gene might be saturated due to inbreeding. So, my strategy was to cross the fish with a different line. But different line of Tosakin was nowhere to be found at that time. Importing again was costly. As an alternative, I had my line of Butterfly that I had been working for several years. I think Butterfly is the best match to cross with Tosakin. From that point, I would cross the offspring back to Tosakin to produce genetically more vigorous Tosakin.

The transition fish mostly did not display the telescope eyes in F1. Later on, the F2 would produce some small telescope eyes. I used them for my Butterfly project. Those without the telescope eyes are used for the Tosakin projects.

Concerning the tail, these transition fish (Flysakin) displayed many different tail characteristics. Some were quite astounding. Yes, they were meant to be rejects. Yet, my mind could not get rid of the impressive tail displayed. They were like paintings! As I looked back to my breeding activity, I had encountered these beautiful tails over and over again, without being purposefully breed them. And they always captivated my mind. It is true that they have no standard worth – they are out of standard. Yet, they carry rough beauty.

Here are some from my archieves:

The year 2020 was the most intense time of my Flysakin breeding.

The color was mainly grey since I used black Butterfly as one of the parents. There was a need to improve the color.

And this year (2024) I think I have come to the peak of my Flysakin projects. There are still several different tail types, but I chose the closest to Tosakin yet with tail split. Why tail split? The split will make it easier for the fish to open wide and develop its flips. So, it is easier to create a quality one than Tosakin.

Of course, the difficulty increases its worth. The more difficult to get, the more we value the object. In this case, quality Tosakin is much harder to get than Flysakin. So, Flysakin is not meant to be a rival to Tosakin. It is just meant to be a less expensive alternative.

There are four individuals that really stand out this year. I have taken some pictures and videos of them. I hope you will enjoy watching these painting-like goldfish.
