I have an OB Peacock tmale hat mated with a non-descript "yellowish" Walmart female peacock (hand selected by my daughter who calls her miss sunshine so the **** fish is here to stay). All of the offspring are this sad yellowish color, though a few do have a blotch or two on their forehead area. I know I should do the right thing with these guys and put them out of their misery, but do OB babies "blotch up" as they age? I might keep a few on the side just to see what they turn into.
