What Causes goldfish Color To Fade From Red To White? Options

[Samuelphan]

Hi Geert,

Given my limited knowledge in goldfish genetics ... is there any other insight that you can share regarding this genetic "deficiency"?

Any way to tell whether a fish will fade eventually or we really have to rely on "breeder" information? If a breeder dun disclose ... we will never know ... right?

With Best Regards,

i was right with my wild guess ... must try my luck on the 10million jackpot next week with 50cents.

does both of you keep them in clear water?

it's a bloodline problem. cross breeding of different bloodline or unstable brooder stock used during the breeding. u got no way to tell at all unless u breed them.

Hi Geert,

If what you say is true, then Fukami bloodline has some problem (may be a good thing to some). Cannot be 2 of us having the same experience with the same bloodline.

Fukami Ranchu bloodline is a commercial bloodline ! Quality can not be compared with the true hobbyist bloodlines.

Crossing high quality bloodlines is not a problem. Using low quality bloodlines is the problem.

Hi Geert,

How can one determine a good bloodline. I am sure breeder like Fukami can well afford to buy one of these good bloodline to start with.

just like those "hamamatsu" fish lor. How many u see in those lfs got put the breeders' name or not ? all just hamamatsu. all ja-bu-lang gather here gather there and sell as a batch lor.

Fukami got good fish also lah, but pay your wallet dry to get one. It's a commercial farm, just like those Yatomi ranchu many bought lor. yatomi got so many breeders, which one leh, Fukami also one of them ? so all just jam pack into 1 single perfecture name "Yatomi" lor ... commercial grade.

Allow me to add further to this discussion on fading colors.There are three basic requirement needed to retain a good ranchu not only in color but overall beauty and quality
.First is good environment,by far the most important and within keeper’s modification and manipulation
.Secondly,the fish must have good bloodline which have been thoroughly discussed above.Even though a system may be an excellent one,if the quality is not inbred the fish will have a reduced chance of becoming beautiful.This is beyond any keeper’s control and a good understanding of its bloodline is paramount to reduce but can never eliminate the chance of landing a poorly developed fish.
Thirdly ,feeding is very important to maintain and improve growth and color intensity to achieve maximum potential

To further add on the topic on bloodline,the term quality used by dealer or breeder is somewhat different from the keeper.For a breeder the quality of the fish is good because of its parents and bloodline.Many years were spent to create and establish a bloodline with good color,body conformation and body growth.These are achieved through numerous cross breeding to reach their expectation and these qualities are further improved with each future crossing with the breeder never satisfied with what he has achieved.

Keepers should possess the knowledge to see if the fish will reach its potential.Know what bloodline they come ,who bred them .Most of of the time they can make some predictions but even though the keeper may be very knowledgeable,they cannot predict what is going to happen to all the fish all the time.There is still an inherent unknown factor called luck,fortunate ones if you are blessed with a champion or arse luck if you are unfortunate enough to land yourself with a "moron."
