Project # 12: Cow Ranchu Update

At the end of last year when I tabulated my projects ( I mentioned that my Cow Ranchu Project was stagnant. I only had two male fish with weak qualities. They are growing old now, so I must come up with a plan quickly to keep this project going. Let me first show the current state of the two male cow ranchu.

In terms of the curve shape, the second fish is a bit better. But in terms of the pattern and color, the first fish is my choice since it has darker black color with more pronounced pattern (large spot with clear cut borders). This project is about color and pattern, so I choose the first fish as my alpha male.

The plan I had was to acquire several female fish to cross with my cow. I did manage to buy a female cow ranchu, two female calico ranchu, a female tricolor transparent scale ranchu, and a black ranchu. I take this moment as an opportunity to experiment with these crossing to understand more about the cow ranchu variant. Here are the female troops:

This female cow ranchu is nice in picture. But she has several defects. First, she is a bit stunted at the size of 11 centimeter. Second, she has a swimbladder issue which makes her swim sideways sometimes. Concerning the color, it is a true cow coloration with lots of strong black patterns. This is the reason I still use her despite her weaknesses. And she produces lots of eggs when being fed properly. (She competes for food poorly due to her swimbladder issue) I will report the result when the offspring come of age.

This calico has thick backbone, better curve shape, short tail, and larger headgrowth than my cow ranchu specimen. I think those positive points will be good combination to improve the overall quality of my cow ranchu line. Concerning the color, the black patterns tend to be in dot shapes all over the body. This kind of pattern is different from the cow pattern. Even if this fish lost her orange color, her pattern does not belong to the cow pattern. But yes, the black pigment is dense, which is a good point. I do not know what the offspring will be. I have the newly hatched babies with me now, but must wait for them to grow more before I can report the update.

I bought this girl together with the first calico. They are from the same farm. The backbone is thick and the headgrowth is good. The melanin appears in dotted shapes. The tiny tail shape caught my attention. I guess it will be fun to see what will come out of crossing her with my cow. However, this fish has an issue with its deportment, probably due to its structure. She has problem with swimming and will prefer to stay with head down. And she does not lay eggs so far. I will wait for her to lay eggs for a little more time.

This girl is interesting! It is a superb pattern! She belongs to the transparent scale category, but she is not a calico. It is more suitable to categorize her in the tricolor variant. If she lacks the orange color, she will definitely be a beautiful cow ranchu! And a better one than my cow. You see, my cow still has blue color (dark pigment under the skin), but this fish is almost fully milk white! The origin of this fish is also interesting. The breeder in the village is my friend. He mated my cow ranchu line with a sakura that has lots of metallic scale all over its body. And among the offspring, there is only one specimen like this. I am very grateful he let me have this fish. And I think, the sakura that he used in the crossing is not a key to produce this pattern. He can only produce one fish with this pattern! So, the appearance of this pattern in his breed is purely luck, I think. This fish laid eggs once but all the eggs are infertile, to my disappointment. I will wait for her second batch to confirm whether she is infertile or not. Hopefully not. And if she is fertile, there is still a doubt lingering in me that crossing her with my cow might not produce the desired result. Well, let’s see.

I always have a question if the production of cow ranchu involved black ranchu in the first place. So, I want to cross black ranchu with my cow ranchu to see what will become of them. And yes, I have the offspring ready to report. I just need to find time to take the pictures. Please wait patiently.

So, this is the update of my cow ranchu project. Still struggling. But I hope you find these attempts interesting as I do.
