Platies are a type of freshwater fish that are popular in aquariums. They are a member of the livebearer family, which means they give birth to live young. Platies are known for their bright colors and patterns.
Most platies will reach about 2-3 inches in length when fully grown. However, there are some species that can grow larger, up to 4 or 5 inches in length. The size of a platy also depends on the specific species and the conditions in which it is kept. For example, if a platy is kept in an overcrowded tank, it may not reach its full potential size.
