How long does newborn molly fish grow into an adult?

Newborn molly fish usually take about 3-4 months to grow into adults. However, their growth rate can be affected by various factors, such as water temperature, food availability, and genetics. In general, warmer water temperatures accelerate the growth of mollies, while cooler temperatures slow it down. Adequate nutrition is also important, as fish that are underfed or malnourished will take longer to grow and may experience stunted growth. Additionally, some molly fish varieties are naturally larger than others and may take longer to reach full size. Genetics can also play a role in growth rate, with some mollies having a predisposition for faster or slower growth.
