Environment and Aquarium: Mollies thrive in well-maintained and spacious aquariums. An aquarium of at least 75 liters is recommended for a small group of Mollies, as they appreciate swimming space. Dense vegetation, hiding places and open areas are appreciated. Using live plants is good.

Temperature and pH: Mollies prefer a water temperature between 24°C and 28°C. It is essential to maintain a stable temperature for their well-being. When it comes to pH, a range of 7.5 to 8.5 is generally suitable for Mollies. However, they can tolerate moderate variations in these parameters, provided the changes are gradual.

Water hardness: Water hardness, measured in degrees of total hardness (dGH), should ideally be between 10 and 20 dGH.

Behavior: Mollies are social fish that thrive in the company of their peers. It is recommended to keep them in groups of at least three individuals to avoid any stress. Intraspecific behavior may vary, but in general Mollies are peaceful fish that coexist well with other compatible species.

Mollies are also known for their tendency to swim in the upper part of the aquarium. They are active and explore their environment. Swimming behavior can vary between graceful movements and more lively moments, particularly during the mating period.
