In the wild, the Molly is found in environments influenced by tidal waves. The environment created by a tropical flood or stream emptying into the sea is a typical Molly habitat. This means that your Molly will do much better if you keep it in a brackish aquarium. Mollies are capable of surviving in a fresh water aquarium as well, but will be more vulnerable to diseases. If you want to keep Mollies with other species, it is therefore recommended to choose other tropical species that tolerate a little salt, such as the Platy. 1 or 2 tablespoons of salt for each gallon of water is suitable.
You can buy marine aquarium salt in most pet shops and fish stores. Frequent water changes is a must, otherwise salt will build up in the aquarium. Since the Molly is a tropical fish, the water temperature in the aquarium should be kept in the 75-80 F range. Avoid including driftwood in your aquarium decoration, since driftwood makes the pH lower. Mollies require a pH between 7 and 8. More suitable decorations are plants and rocks. When you decorate the aquarium, leave a larger area of open water for the Molly to swim around in.
The female is white with black dots, and the male is black with white dots so I call them ying and yang She’s yang. The male is soo protective, he’s staying close to the breeding net with his dorsal fin fully extended, chasing any fish away that shows any interest in his babies. He’s the alpha male of the tank about 5″ long. I have another male slightly smaller, on occasion they fight over the females. They don’t hurt each other, some gentle nudging and displaying of dorsal fins, they are both sail fins.
