NEO intex literally means: natural, energy-optimised nutrition. Behind this lies the ratio of proteins to fats in the food. Looking at the season alone, the fish would only need half as much protein in winter (2:1) as in summer (4:1). But because not only the season (meaning the water temperature), but also the size and age of the fish, and food function (e.g. growth food = ProPond Growt) play determining roles, the der NEO index has been developed to deal with all these factors in one.
The fish’s living conditions are also incorporated into the NEO index and factored in the different function foods. Thus the prebiotic ingredients of JBL ProPond Fitness provide ideal conditions for good health, even when the temperatures are varying wildly in times of seasonal change! The protein/fat ratio of 5:1 in the food helps your fish to compensate for their high metabolism without drawing on their energy reserves. This way they have enough energy to fight diseases and other issues.
Along with size, age, season and water temperature the fish species also plays an important role, of course. Koi and goldfish are physiologically-nutritionally very close. That’s why goldfish can be perfectly fed with koi food during their whole life. Koi have a higher demand on the food since they often need to develop more varied and brighter colours.
