      Long fin koi

      Hello!!

      I live in Norway.
      Here in europe long fin koi is not very common.

      I have just received a long fin koi from Japan, that my koi dealer
      arranged for me.
      The breader is Yamazaki.
      I think they look beutyfull!

      I have tryed to find out hwat is the differense between standard koi and long fin koi.

      I general they are the same rase / the same latin name.
      beside the fins I found the below on Wikipedia.

      Butterfly Koi originated in the mid-20th century as a result of an effort to increase the hardiness of traditional koi. Japanese breeders interbred wild Indonesian Longfin river carp with traditional koi. The resulting fish had longer fins, long barbells, pompom nostrils, and were hardier than koi. These were known in Japan as "onagaoi" or "hire naga koi", or translated in English "long tail koi". Randy LeFever, the son of Wyatt LeFever, a noted breeder of koi, is credited with suggesting they looked like butterflies, a trait for which the breed is named. They are also sometimes referred to as Dragon Koi. They do not get as big or live as long as normal Koi.

      This left me with even more questiones

      Hardier in what way??
      Minimum temp they can survive??
      How long do they live??
      How large do they become??
      All info is good info.

      That looks a lot like my butterfly Koi, I have searched and searched on the internet trying to find one that looks like mine and figure out what kind of Koi he is. I got him last year and he was about 3" long, now he is well over a foot long, maybe close to 18" now, and his head and mouth are huge, he has outgrown the other fish by a mile, so I don't know what they are talking about when they say they don't get big. He was a very vibrant metallic gold color when he was small and now he is cream colored and very friendly. I have one other butterfly and a regular Koi as well. I would love to know what he is, I'm thinking Ogon? I'm sure some of the experienced Koi keepers will jump on here and give you some answers, I'll be watching as well.

      Blue Ridge Fish Hatchery in North Carolina were one of the early US developers of long finned koi, which they named "butterfly koi". Pan Intercorp has a history of longfin development in Japan. Longfins are a hybrid between Cyprinus carpio and an unnamed long finned wild carp found in Indonesia. Since the offspring of these hybrids are fertile, it is likely that the unnamed wild carp will ultimately be determined to be a race of C. carpio or is at least extremely closely related to C. carpio.

      Hello Cheryl!

      I bought it as Gin Rin Platinum, and I guess it is a Gin Rin Platinum :-)
      It is a Tosai and is now 12" long.
      It is very hungry and friendly. After only 4 days it is allmost eating of my hand :-)
      It is now in "quarantine" in My gold fish aquarium that is 200l.
      I exchange 50l of water every day!!

      I started the koi hobby last summer.
      My pond is not sufficient to winter the kois outside. so they have been inside all wnter 22 deg C.
      I bought 4 kois that was between 4" and 6".
      Now my bigest Chaigoi will be 16" in one or two weeks

      Thank you Rick!
      The blue ridge link was very interesting.

      They are more healty, and have a better resistance against disease.
      I found som info. about that they are fast gowers.
      How big do they grow??
      How do they handle cold winters??
      How long do they live??
      How large do they become??

      I have many longfin/butterfly koi. Most of mine came from Blueridge koi (Wyat and Randy LeFever). I also have a few from Suda and Yamason. I have had the ones from Blueridge for many years and have many offspring from them.

      I have found them to be as hardy as regular koi, but can not tell that they are hardier than reqular koi since for me both are generally hardy once I get them through the first year.

      I have some as old as my oldest koi which are 18 years old. They have been in water down to 33 F degrees but my ponds do not stay at temperatures that low for more than a couple of days.

      Some of mine are near 30 inches long and some will never be very big. I have some here that are quite old and 8 to 12 inches and others from the same spawn that are some of my largest.

      Other than turning them over to see what sex they are; is there a way to sex them as there is with regular koi? (Ie fins, body type)

      When started in the hobby, the local fish store handled longfin (butterfly) koi only. Our first year fish were all longfin, and those bred and produced these two either the second year or the third year we were ponding. We started in 1996. That net is a 30" net for reference on size. These pictures were taken in 2007 and they are still with me. None of the newer pictures are in tub or net, and are not resized.

      Not a whole lot, by then they were almost 10 years old.

      Thank you for your answers.

      So.... They are just as "normal koi" more or less :-)

      Rich Please post more pictures :-)

      Is there anything that I should consider / any tips i will need when taking care of long fin koi?

      I will winter them inside as I all ready have done this year. five months with up to 40" of ice is hard on the fish, long fin or not.

      The biggest issue is the tenderness of the fins. They will split readily and it takes a long time for them to grow out losing the split. The ones I started with were survivors, when I started killing Japanese standard fin koi. Too many fish, too little water, and no understanding of the cycle.

      Richard:
      What is the main reason for the fins to split?
      Does it hurt them / do they get a handicap if the fins split?

      Do you mean that the long fins are more resilient to water quality?

      So wintering seems to be similar to regular koi :-)

      The longfins should not be moved in a net once they get some size on them. Their fins split easily in a net when they thrash around. It is best to guide them into a bowl or container with water.

      Cold water may cause their tails to have red streaks. It does not last long here since I do not have prolonged periods of cold temperatures. I do not know how this will effect them long term in long periods of cold temperatures. Sometimes other stresses can cause red streaks in their tails. The red streaks I believe are the blood vessels in their tails. Many of my koi have very long fins and tails and this is seen most often in the longest tails. It has not caused any problems with my longfins and usually disappears in a few days without any ill effects that I have observed.

      I think the tears are a combo of nature/nurture/genetics. I recently sold my last one. At roughly 5 years old the fins were in tact despite netting, bowling, and baggin. Other prior LF koi had split fins as tosai. The same 5 year old koi's growth slowed massivley and the last year it finally made it to 16 inches (tail fin excluded). My standards were getting to that size by the 2nd year, so I do believe they lack growth in general when compared to standards. There are exceptions when the owner provides great living space for them. I remember two years ago at a show there was a Showa LF that was somewhere from 24-30 inches.
