Mollies are shoaling fish, not schooling fish, which means that although they tend to travel in groups, they do so more for social purposes than for traveling in specific directions with each other.
The most common varieties of this fish typically available for aquariums are the common molly, the black molly, the white molly, the sailfin molly, and the Mexican molly.
The male species, who tend to be much smaller than female mollies, have a specialized anal fin called a gonopodium. This rod-shaped organ is used to deposit sperm in female mollies, who can retain it for extended periods of time.
They are considered tropical fish which means they prefer warmer temperatures. The recommended temperature range to keep this fish in is anywhere between 70 and 80 degrees Fahrenheit.
They are sometimes confused with guppies who are in the same family.
