After many years of studying the nutritional requirements and finicky eating habits of bettas, Hikari introduced Betta Bio-Gold. Packed in an easy-feed, card type package that was developed because we found many betta keepers overfed their fish, Hikari Betta Bio-Gold offers your betta all the nutrition they need for a long and healthy life. There's a reason Hikari Betta Bio-Gold is loved throughout the world, it makes bettas happy and the owners who keep them even happier!
