Pink gene and the white gene are the samething, some people call them pink and some call it white. My female is a pink/white marble and my HRP male was carrying the pink/white gene because now that the babies are free swimming i can see more pink/babies this will be very interesting to see how they grow. Im in awe with how great these 1inch parents are taking care of there babies, she is the best and she will be here for a while and i will be pairing her up with alot of different males to make some nice hybrids.
