Hello,
$300 is a good deal provided that you can keep the quality in the next 2 years by then she will be ok. I didn't have that kind of luck with Ogata kohaku except from the girls I got from JO Co. It is a regular thing for Ogata koi to exceed everyone's expectation while their 2 years old. Once the water quality goes down they will be the first one to go. Again genetics comes into consideration. That's just my observation........
