Hey Lei, another great video! It will come as no surprise that your video has set me to think about a few things and I had a couple of thoughts and a question or two. First let me say that I am in total agreement with you on the role of early and frequent culling as a useful tool in the belts of breeders and hobbyists alike. As a practice for maintaining adherence to breed standards, keeping breeding lines healthy and eliminating harmful genetic defects it’s value can not be overstated. I do however think that in cases of minor non-genetic defects such as tail curl and folds its use seems drastic especially when the fish is otherwise healthy, and it’s quality of life is not affected by the defect. In the more serious defects affecting the skeletal framework of the tail I can see a valid use on a case by case basis but for many of the cases of curls and folds you outlined I fail to see a need to kill fish where there is no issue to the health and well-being of the fish and would also eliminate a relatively lucrative line of revenue for a breeder who by marketing these “less than perfect” examples as higher quality alternatives to the masses as pets; it certainly be an improvement to the mass produced low quality goldfish sold in the Walmart and K-mart pet departments. By exposing people to what truly higher quality pet goldfish can be we would get breeds in the hands of new hobbyists that they’d never be able to afford or have even seen. By increasing the diversity of offerings available it would force retailers to finally begin stocking proper equipment to house these animals and see the end of the goldfish bowls and the “carnival pride gag gift “mentality that is so pervasive in the minds of the uninitiated. Let’s face it, most of us could never have a $6000 show quality Pan’s Milk Cow Ranchu but “a less than perfect” aka minor non-genetically flawed Pan’s “Moo Cow” Ranchu line at $50 would have been something I could have aspired to if it had been available when I was a 15 year old with my first aquarium and all our local Kmart offered were Comets in gold at $10 and $15 Calico Fantails that on a good day they may have even swum upright. I totally understand that these defects to a seasoned hobbyists would not be desirable especially if they are looking acquire a breeding pair but I definitely think that the hobby would be in a far better place today if we focused less on a fish’s physical perfection and more on the health of the fish and it’s well-being. I certainly think that there would be more kids with properly housed and cared for Sakura Bristols than Calico Comets in woeful inadequate “goldfish toilet bowls” prisons swimming in their own filth. I’ll get off my high-horse now and ask a question that’s been nagging me and I was curious as to your experience - if, as you pointed out, there are preventative interventions that can minimize the occurrence of these tail defects are there remediations that can reverse them once they’ve occurred? Can a tail that has developed a curl or fold ever be rehabilitated?
wow, Bruce. Those are very insightful points. I can't help but pin your comments again! I have not thought about the side effects that you pointed out. I need to emphasize that these tips are more for awareness. These issues are the most minor defects of goldfish. For most of goldfish hobbyists, the folded or curved tails should not be a big deal as long as the goldfish are healthy. To answer your question, my answer is yes but with some risk. Once the folded tail and curved tail are developed, you may heal it by cutting the corner of the damaged tail and hope to regrow. In most case, the tail tip will grow out but with some risk. Thanks again.
I eagerly await your next video … I must admit I don’t get to think as hard as I do in the absence of your thought provoking and insightful offerings :) Cheers my friend and all the best to you and your family this Christmas and New Year!
I wonder if the type of tail can depend on the body type of the goldfish and the clarity of the tail in theory might correspond to goldfish's swimming speed? In more fragile tail types like a tosakin's, slow speed and chubbier body keeps the tail form stay put. I think in wakin-type fish like commons, comets and jikins where tails in swimming are sturdy and straight, a folded tail may cause the frame to collapse and appear ugly, and it might not be easy to obtain in such vigorous swimming fish rather than elegantly slow moving fancies.
I think environment may play a big role. Tosakin has a big tail not caused by its big body but trapped in a constrained small tank. If you leave tosakin in a big pond, the tail will become slim
Thank you for sharing knowledge and education about goldfish, increasing my knowledge about goldfish, polite greetings from friends of goldfish farmers in Indonesia, happy New Year
Great point. Sarasa comets are some of those fish that resemble swimming kohaku butterfly koi. A comet bred with red/white colors and the diversity of it is perfect
Omg yay, another Goldfish Corner video! I have a question that maybe you can help. Do you have any recommendations on books to learn about goldfish breeds and where they came from? I want to learn about all the breeds, and whether they were bred from an older breed, or made as a cross-breed. It feels like some breeds are hardly talked about in the U.S. I am wondering if there are any resources from other countries that have been translated to English. (I have been working on a "family tree" of goldfish breeds, but many sources are incomplete or contradict each other)
Hi Juliet, sure. The best book about goldfish genetics is written by my alumni Dr. Joseph Smartt. Goldfish Varieties and Genetics: Handbook for Breeders. Amazon link: amzn.to/3GJ8fLI
@@GoldfishCorner Thank you! I have "Goldfish Breeding and Genetics" by Joseph Smartt and James H. Bundell, which I think has a lot of similar info. I will review it again and compare it to other sources. Someone recommended "Goldfish Guide" by Yoshiichi Matsui to me. It feels like some varieties are not in a lot of literature so it is hard to learn about them. I did not know about the types of top view ranchu until you had them in your ranchu video.
@@thrice42 Matsui's " Goldfish Guide" is a really good book. I have one. It has a detailed discussion about different breeds and one chapter on goldfish genetics. Good choice. I would recommend it.
One of my goldfishes has an unsymmetrical tail, its a ranchu and still very young. One of its tail fin and a lot smaller than the other. It's almost certainly a birth defect but outside of that, is it something I should be worried about? I looked online and haven't been able to see too much on this topic. Hopefully it will do alright and fit in with my other fishes, one of which also being an oddball, a ranchu with the bubble eye mutation. I didn't notice it when I got him until a few hours after being home I noticed some "air sacs" under his two eyes, one being larger than the other. I thought it was sick and tried to treat him lol, turns out it didn't bother him and he is still kicking it 9 months later.
Excellent contribution, once again something new to see and take into account in the breeding of Goldfish. Friend, if you could ever address the topic of scale types in Goldfish, it would be excellent.

Great info, this is a little peek into real Goldfish keeping.
Thanks.

These analyzes on the deformations of goldfish tails are really interesting.
Happy weekend dear Lei
Thank you Marco.
Nice sharing kaibigan
Thank you, Happy new year 🎊
Liked this informative video! It’s easy to understand with the effects😊
Another great video! Thanks for sharing!
Thank you my friend
Very informative
Thank you

Thank you my dear friend from Indonesia 🇮🇩. Happy new year 🎆
Sir if you could give a topic on sarsa comet goldfish variety.....
Thank you for the suggestion
