Molly Tank Setup

Question
I have 3 short finned Mollies need some advice about tank setup I need the budget to be around $50. I don't know how big the tank would be, maybe a couple gallons. I'm planing to put in some plants so the two females can hide from the male I don't want a lot of fry.

Answer
The minimum size tank for the three mollies is 20 gallon. You will need a heater set between 78 and 80 degrees and a filter. There is a wide range of plants that you can add. Also, mollies are a brackish fish, which means, they need some salt in their water. As for the fry, as long as there are males and females in the tank, you will have fry every 21 to 30 days. Even if you remove the male, the female can hang on to sperm from previous breeding, for about 6 months and sometimes longer.
