Information on Keeping & Caring for Molly Fish
When keeping Mollies, the best water conditions are tank water temperature of about 80 Fahrenheit with pH values between 7.5-8.2 and hardness of about 15-30 dGH. Adding up to 1 tsp of aquarium salt for every gallon of water will help promote good health and extend the lives of the mollies.
Mollies are very social fish and great additions to community tanks. They will mix well with other mollies, live bearers and peaceful fish that are similar in size.
