Apple snails can generally grow to about 2 cm in length. There are some larger individuals, in a suitable environment, the body length can reach about 2.5 cm, but basically can not grow to 3 cm. How big they grow depends largely on genetic and environmental factors. Individuals with good genes can grow larger in the right environment. And if the cultured individuals have poor genes, or the culture environment is not up to standard, they will not be able to grow so large.
After the apple snail is born, it takes about four months to grow before it can have reproductive capacity. But there are also some precocious individuals, which may be able to reproduce at a younger age. Whether they can reproduce is related to environmental factors besides age. If the water quality is high and the water temperature is suitable, they can reproduce normally. If the water is too dirty or too cold, they can't breed.
The reproduction frequency of the apple snail is also related to the environment. If the water temperature of aquaculture water is between 20-28 C, they can reproduce normally and reproduce several times a month. And the higher the water temperature, the higher the frequency of reproduction. If the water temperature is about 18 degrees Celsius, their reproductive frequency will be reduced. If the water temperature is very low, they will not breed.
