The cause of overcrowding of guppies in the aquarium is typically due to overpopulation. Guppies are known for their rapid reproduction, and if the aquarium is not properly managed, their population can quickly grow beyond the capacity of the tank. Additionally, if the aquarium is too small or lacks adequate hiding places, the guppies may feel crowded and stressed, leading to aggressive behavior and further population growth. It is important for aquarium owners to monitor the guppy population and provide a suitable environment to prevent overcrowding. **
