Update on Tricolor Ranchu project.
I finally kept only two male fish from this project. They are semi-ranchu (ranchu with a defect dorsal) but with good intense black color. The black pigment has grown since, defying the demelanization process! Here are their development from six months ago.
First fish previously:


Now:


Second fish (previously):


Now:


If I do not follow their development closely, I might not be able to recognize them. The black color is expanding, and also the orange color! Both fish lost some of the white color in their tails to become orange! The second fish lost its white color on the cheeks. That is an amazing phenomenon. We can still recognize them from their awkward back bone shapes.
Interesting to note that the first fish has a goosehead type of headgrowth while the second one has a lionhead type.
I mated them with their female sibling, which died after that. I mated them back with a tricolor oranda (no picture). The result is great in terms of color. But the dorsal appears fully again. These are two of the results from the tricolor oranda cross:




They have superb colors, don’t they?
The first offspring is my favorite. She is the female I crossed back to the two father four days ago. I do not hope for a decent ranchu shape at this stage. I will settle for a defect dorsal but with good tricolor quality.



The second offspring is a male. There is no point in mating him with the sibling. I mated her with a grey ranchu from my previous failed tricolor project. The backcurve is decent enough, but the tail is weak. It has tricolor gene in its grandparent.


Want to see the results? Must wait for several months to come. Hopefully it will look like this (I clear out the dorsal using Photoshop):

I have a question about goldfish eggs. Do all
fertilised goldfish eggs stick to a surface? Can some fertilised egg still be free floating?
I always assume that free floating eggs are not good and throw them away. But I never try to see whether they can hatch or not. So, sorry, I can answer based on assumption.
