Used this for a show preparation. The fish looked fuller and more vibrant. The ingredients seem high quality. A bit expensive, but worth it for show purposes.

Good for increasing body mass. The fish eat it eagerly. Works well in winter too. A bit more expensive than regular koi food, but the results justify the price.
