But if you provide them with proper water conditions and meet their requirements, they will live longer and happier.

Mollies are not just a single fish, but a group of fish falls under this category. These fish belongs to the family Poeciliidae and are about 40 different types of Mollies. Usually, all these Mollies fall into the three categories of Mollies: Shortfin Mollies, Lyretail Mollies, and Sailfin Mollies.
Moreover, some examples of Mollies are:

- Blue Mollies: Blue Mollies are very similar to the albino Molly Fish but with a blue body.
- Gold Mollies: The gold molly has a solid golden color and may or may not have any spots on its body.

- Orange Mollies: The orange mollies has a bright orangish hue with either an albino or gold body.

Do Molly Fish Like Living With Other Fish?
Mollies are social, so that you can keep them in pairs or larger groups. They will not bother other species of tropical aquarium fish if you provide them enough space to live comfortably.
Mollies prefer living with guppies, platys, swordtails, bettas (male only), and most tetras as long as they have a place to hide. They are peaceful and can live with other non-aggressive species of tropical aquarium fish.
However, Mollies are not compatible with betta fish. These fish will nip at the fins of other tropical aquarium fish, and this can potentially cause injuries. Sometimes the fin nipping behavior of Mollies also leads to fighting and even death.
So keep Mollies only with the fish that do not provoke or disturb them. Such as corydoras catfish because they feel safe when hiding among their barbs.

Mollies also do not fare well when kept in an overcrowded aquarium. So be sure your stocking levels are appropriate for the size of your aquarium. They are usually peaceful, but they will eat smaller fish that fit in their mouths. It is best to keep them with other non-aggressive species of similar size and temperament to avoid conflict.
