This female has blue on tail fin.
Is it okay to assume that this fish has Japan blue and gene responsible for doublesword(maybe elomgatus )on X chromosome?

I still have japan blues overhere. But hopefully by next week, they'll be gone. I need their tank for a new project. And an lfs wants to have all of them.

I am happy that I could find this strain.
