white fin on yellow lab?

[missie]

So, Recently realized one of my yellow labs was beaten up pretty bad in the main tank. ...I bought a tank divider for a smaller tank and gave "sunny" his own space to heal is nipped fins. his fins have begun to heal HOORAY! Ok, to the point- one of his fins on his belly, towards the back has turned completly white. Not its normal colors!
parameters are amm 0/ph 8.4/nitrite 0/ nitrate 0 . eating and acting complelty normal... Only new thing is rearanging substrate like crazy! any idea why his fin has turned white?? Ive never seen that before!

a lot of the time when a fish grows back its fins after serious damage it has no coloring, its just scar tissue. one of my yellow labs has white tips on his back fin and a white patch on his side from being badly bullied by another lab.
