Best Companions for Mollies

1. Guppies

Guppies are a fantastic choice to coexist with mollies. They are similar in size and have similar water parameter requirements. Both mollies and guppies prefer slightly alkaline water with a temperature range of 75-82°F (24-28°C). These colorful fish can create a stunning display in your tank.

2. Swordtails

Swordtails are another suitable option for a molly tank. These fish offer a contrasting shape and color pattern, adding visual interest to the tank. Like mollies, swordtails prefer slightly alkaline water and can tolerate the same temperature range.

3. Platies

Platies are peaceful, easy-to-care-for fish that can get along well with mollies. They come in various colors and can add a vibrant touch to your aquarium. Platies are hardy and adaptable, making them a great choice for beginners.

Fish to be Mindful of

While there are several compatible fish, it’s important to note some species that may not be ideal tank mates for mollies:

1. Angelfish

Angelfish can be aggressive and may view the mollies as threats or potential food. Their tall and slender shape can also make them prone to chasing or nipping at mollies’ fins.

2. Betta Fish

Betta fish, also known as Siamese fighting fish, are territorial and can exhibit aggressive behavior towards other fish, including mollies. It’s generally best to keep bettas in separate tanks to avoid any confrontations.


Choosing the right tank mates for your mollies is crucial for a harmonious and enjoyable aquarium. By considering factors such as compatibility, water parameters, and behavior, you can create a thriving community tank where your mollies can coexist peacefully with other fish. Remember to monitor the behavior of all the fish in your tank and make adjustments as needed to ensure a stress-free environment for your mollies and their companions. Happy fishkeeping!
