I was just wondering, do different scale types and fin types live as long as normal koi?
Now, I understand the bar for that is pretty high, with the longest lived koi being 226, but let's just look at the usual 20-30, possibly 50 years for now.
The longest lived koi was also a chagoi if that makes any difference. To me the breed itself is a biological anomaly, because in spite of them being extremely large and fast growing, they are usually the longest lived from what I've heard.
I have heard that doitsu, the scaleless ones, develop more issues overtime because of the fact that they are primarily to completely scaleless, in regards to water quality and injuries. However I have also heard that because they don't have scales, they don't run the risk of injuries related to whenever scales get knocked off, and the fact that they have better immune systems because they are derived from the outcrossing of traditional koi to german mirror and leather carp.
On the other hand, butterfly koi, I have heard also have stronger immune systems for the same reason, except they were the result of breeders crossing traditional koi to the long finned common carp that "occur" in Thailand. However, what I can expect and understand that I have heard, is the fact that the extra weight of the longer fins in some lines, combined with the fact that these fins drag at a certain length and subsequently tear, (and in some cases combined with the fact that the longer finned lines are heavily inbred for the trait) would consequently counteract the restored integrity of their immune systems as a result of the outcrossing.
What are your thoughts and experiences on the matter?
