Don't give up yet, it's a nice looking little koi. Try not to throw food on top of him, but rather scatter food in a few areas so that he can dash up to get some without feeling like he needs to compete with the bigger koi. I had a tosai like that and once she hit stride, she made up for the growth in the months that followed. She ended up being one of the largest in my pond.
