perc color question

[debbie]

Hi, my two new percs are doing just great. Must say I love these little ones....:yes:
I would like to know why the smallest one is a brighter orange than the bigger one?
Because there is the size difference will they breed? If so is it possible to raise these fish in an aquarium?
:happyfish :happyfish

The darkness/lightness of the fish's color doesn't depend on if they are bigger or smaller in the pair. It's just the color they are born with, like people are born with brown, black, red, blonde, etc. hair.
They can breed, and it is possible to raise the fry but highly not likely in the display tank.
