Males fishes can gain up to 3-inch length but the female can grow 1x more than males. They can live up to 5 years of life if they are provided with an ideal tank Setup.
Ideal Tank Setup:
For a perfect tank setup, first of all, we must consider the quantity and ratio of fishes we are going to keep in our tank. The ratio of two sexes can put you sometimes in a very hectic situation. Because the males are aggressive in nature and keeping 2x to 3x will harass your females. Because they are peaceful and can be stressed easily.

People said that Black mollies are brackish water fish but that is not true at all. They can survive in all types of water. Freshwater tanks are a good choice for them. They love to swim in the water all the time so they need space for swimming in the tank. You must have a good tank size to keep them. 20-gallon tank size is the least tank you must have in order to keep them but the large tank (4o to 50 gallons) is preferable.
Water is the main thing to consider for your tank. Mollies are sensitive to water parameters (Temperature and PH). The PH level must be maintained between 7.5 to 8.2 which is the alkaline nature of water. All livebearing fishes need optimum water temperature. Mollies also give birth to live fish fry so they need 21 to 26 Celcius.
As we know that they love to live in freshwater, that is clean and clear. For keeping it clear a filtration system is needed. You don’t need a much expansive filter, You can go with the Cheap hang on a back filter which will not disturb your water top surface at all.

Whenever you noticed that Mating has been done. Wait for at least one or two weeks, After that move your female molly in a separate tank (Breeding Tank) So it can give birth to healthy live fry. Otherwise, Other fishes in the tank will eat them as you know most live-bearing fish do not have any parenting habits.
