The skin of shrimps and crabs is made up of chitin. Since the skin of these animals does not grow as the animal grows, they molt regularly. To make new skin, shrimps eat chitin from their old, discarded skin or cellulose from plant-based materials. HS Aqua Crusta Chitin+ is a product made from natural shrimp skin that helps these animals create new skin. Add a small amount of HS aqua Crusta Chitin+ to the aquarium 3 times a week.
