He was definitely priced on the low end and i wasn't sure if he had Yellowbelly in him because it can be a subtle trait especially in Spinners. I have a business partner that works at NERD, so i forwarded his pics to him and they confirmed that he is a Spinner Yellowbelly. He was also a slow starter, which i think affected his pricing. He was 3 months old, only 60g, but started feeding consistently when i got him.
