What Can Live with Mollies?

Published in Molly Fish Tankmates 2 mins read

Mollies, being peaceful and active fish, can thrive alongside various other fish species that share similar temperaments and environmental needs. According to the provided reference, excellent tankmates for mollies include Barbs, tetras, catfish and similar species.

Choosing Compatible Tankmates for Mollies

Selecting the right tankmates is crucial for the health and well-being of your mollies. The key is to avoid aggressive fish that could bully or harm them. Mollies are generally placid and enjoy a peaceful environment.

Suitable Fish Species

Based on the reference, several types of fish make good companions for mollies:

  • Barbs: While some barbs can be nippy, many species, particularly smaller, schooling types like Cherry Barbs or Gold Barbs, can coexist well with mollies in a spacious tank.
  • Tetras: Most tetra species are peaceful community fish that school together and do not pose a threat to mollies. Popular choices include Neon Tetras, Cardinal Tetras, and Serpae Tetras (though observe Serpaes for fin-nipping).
  • Catfish: Many bottom-dwelling catfish species, such as Corydoras or Bristlenose Plecos, are peaceful and occupy a different level of the tank, making them ideal tankmates that won't interfere with mollies.

These species are highlighted as they typically do not exhibit aggression towards other fish, especially larger ones that might harass or attempt to eat smaller fish like mollies.

What to Avoid

It's important to avoid aggressive species or fish that are significantly larger and might view mollies as prey. The reference specifically advises against "species who exhibit aggression towards other fish, especially larger fish who would harass the smaller mollies and sometimes even attempt to eat them."

Practical Considerations for a Community Tank

Creating a successful community tank involves more than just choosing compatible species. Consider these points:

  • Tank Size: Ensure the tank is large enough to comfortably house all fish, providing adequate space for swimming and territories. Overcrowding can lead to stress and aggression.
  • Water Parameters: While mollies are adaptable, ensure all tankmates have similar requirements for water temperature, pH, and hardness.
  • Diet: Choose tankmates that can thrive on a similar diet, although bottom-dwellers like catfish may require sinking pellets.
  • Temperament: Always research the specific temperament of any fish before adding it to a molly tank.

Adding compatible fish like peaceful barbs, tetras, and catfish can create a vibrant and harmonious aquarium environment for your mollies.
