Maintain black white colour Of Panda Dragon Eye, Is there a special requirement to maintain the colour of Panda Moor? Options

[Ray Ng]

I have tried keeping Panda Moors a few times and most of them ended up being "bleached"; meaning the black color disappears as they grow (usually takes about 6 months). Is there some tips on maintaining the panda look of these moors?

I have one Panda moor kept in an outdoor tub with algae wall and another kept in a sheltered fish tank. Both of them turn white after a while. I was just wondering what could be the right environment for pandas. My setup all uses coral chips and the ph is quite stable.

Just an extra note; panda kept in the outdoor tub begins to show "flesh coloration tint under” its white skin area. I'm not sure whether this phenomenon was a result from feeding too much from the algae wall.

Hope someone can enlighten me

I do not know much either about this problem, but I heard before that increasing the water hardness will strenghten the black color in koi. I guess the same should apply in goldfish? And I always try to employ this tip when selecting young pandas (if we have the liberty to select), that is: choose the one with as little white color as possible. Hopefully when it grows up, as the white area becomes larger, we will still have a good percentage of black color in it.
I asked a breeder friend if we can enhance the black color by crossing panda with blackmoore, and he said he did it before. It worked, but, and this is the drawback, the young fish will mostly look totally black, just like blackmoores, and the white will come out very late. This prevent the breeder to sell the young offsprings as pandas (cause no apparent white was seen). People couldnot see it as pandas. And the breeder stopped doing such things for it is not profitable for him. I myself have no experience to confirm it, but surely this is interesting At least this might enable us to get a panda color in a mature fish
