In the first year of their birth, razor turtles need to be fed every day, and it is best to feed them twice a day. Because the first year of their birth is the golden stage of their growth and development, breeders need to feed them a lot of food to ensure their adequate nutrition and make them grow bigger. In the second year, they need to be fed once a day, because they are still in the development stage. Although the development speed is not as fast as that in the first year, they should also ensure adequate nutrition. When razor turtles mature, they don't need to be fed every day, because their body shape and organs have matured, and the food and nutrition needed will be reduced, so breeders can feed them once every 2-3 days.
