So far I think I have succeeded in producing purple goldfish, or purplish one, or any other name differentiable from blue and brown (chocolate). At this point, I think I can wrap up this project and consider it done. What remains is to try the same project again but with different type of fish. What I have in mind is ranchu. I would like to create purple ranchu. But first, I need to create the chocolate ranchu, which is still my ongoing project. It will be a challenging project!

There is another observation coming from this purple goldfish which I am not ready to share yet. Let see for another year or more if this observation really yields something interesting.

Have a good day!
