Mealworms are ideal food for reptiles such as chameleons and lizards, and large tropical fish and ancient fish such as arowana. Bran, which serves as food and bedding, is essential for raising mealworms. By mixing it with unfermented mat and fermenting it, it can also be used as an additive for the larval mats of rhinoceros beetles and stag beetles. What is bran? The outer skin of wheat. The process of making wheat flour from wheat begins by coarsely grinding the wheat, and then repeatedly sieving the wheat flour and other parts while finely crushing them. The remaining 80% of the wheat after sieving is the bran that we are selling this time. It is also used as a mushroom substrate. It is used as a carbon source in mushroom substrates for the nutritional growth of mushrooms. In addition, it has a coarser particle size than rice bran and is also used to adjust the physical properties of the substrate. It comes in a 280mm (below the zipper) x 200mm zippered polyethylene bag. The product will be placed in a kraft envelope, a shipping label will be affixed, and it will be shipped. (It will be dropped off at a nearby post box.)
