The quality of Hikari® diets is a direct result of the many activities undertaken to understand fish, their eating habits and their dietary requirements. It all starts with exploration to study the actual habitats of tropical fish. This invaluable experience compliments intensive research by our Hikari Aquatic Laboratory staff. Additionally, our world renowned Yamasaki Koi Farm, tropical fish breeding facility, marine fish breeding facility and crustacean breeding facility allows allows us to use our diets first hand, ever noting the growth and coloration characteristics each one offers. We are also the largest shipper of live tropical and marine fish in all of Japan. So, as you can see, we are not producing diets for the sake of selling merchandise, but rather make the health and longevity of the fish and the health of the aquatic environment they live in our first priority. Focusing on bringing about success to the hobbyist through exacting nutrition has allowed us to develop a brand name synonymous with superior quality!
