Can Mollies and Angelfish Live Together: (Problem Solved!)

Mollies and Angelfish, known for their vibrant colors and peaceful nature, are famous among aquarium enthusiasts. But can these two species coexist harmoniously in the same tank? The answer is more complex than one might think.

Mollies are known for their playful and social behavior, while Angelfish are admired for their graceful appearance and elegant swimming patterns. Both species are generally non-aggressive and can thrive in a community tank with other peaceful freshwater fish. However, certain factors must be considered when contemplating keeping mollies and Angelfish together.

In this article, we will explore the compatibility of mollies and Angelfish, including their behavior, tank requirements, and potential challenges of keeping them in the same environment.

By understanding the needs and characteristics of both species, aquarium enthusiasts can make an informed decision about whether these two fish can peacefully coexist in the same aquarium. 

Overview of freshwater angelfish

Freshwater angelfish, or Pterophyllum scalare, are popular aquarium fish for their distinctive appearance and graceful swimming patterns. These fish are native to the Amazon River basin in South America and are often found in slow-moving, heavily vegetated waters.

Freshwater angelfish are known for their tall, triangular bodies, long trailing fins, and striking coloration, including shades of silver, black, white, and yellow. Both species of fish are peaceful and do well in community aquariums, but they can be territorial when mating.

Angelfish are omnivores and will eat various foods, including flake, pellet, freeze-dried foods, and live and frozen options. They require warm water and a well-maintained aquarium to thrive, and careful attention should be paid to water quality and tank maintenance.

Freshwater angelfish are a beautiful and intriguing addition to any freshwater aquarium. 

Are mollies and angelfish Great tank mates?

Mollies and Angelfish can generally coexist peacefully in the same tank. Mollies are peaceful, active fish that prefer to swim in the middle and top of the tank, while Angelfish are also peaceful but tend to stay closer to the bottom. Both species have similar water parameter requirements, making maintaining a healthy environment for both easier.

However, Angelfish can become territorial during breeding and may become aggressive, so it’s essential to provide ample hiding spaces and ensure no overcrowding issues in the tank.

Additionally, mollies are known to be prolific breeders and may produce more offspring than the tank can handle, creating overcrowding and potential stress for the Angelfish.

With proper fish tank management and consideration for potential territorial behavior, Mollies might make great tank mates for your Angelfish and create a harmonious aquatic environment. 

Can Mollies and Angelfish Live Together?

Mollies and Angelfish can coexist cautiously in a large, well-decorated tank (55+ gallons) with ample hiding spots. Be mindful of:

  • Predation: Angelfish might nip smaller mollies or fry. Choose larger molly varieties like sailfins.
  • Competition: Provide enough space and ensure balanced stocking to avoid territorial squabbles.
  • Water: Adjust hardness and acidity to find a middle ground for both species.

It’s not the easiest pairing; alternative tank mates might be better for beginners. Monitor closely for aggression and be prepared to separate if needed. Prioritize the well-being of your fish!

Angelfish and Mollies: Habitat and Tank Requirements

Angelfish and mollies are popular freshwater aquarium fish but have different habitat and tank requirements. Keeping them together successfully requires careful planning and consideration of their needs.


  • Habitat: Angelfish are native to the Amazon Basin and prefer slow-moving rivers and flooded forests. They enjoy densely planted tanks with plenty of driftwood and rocks for hiding and spawning. The ideal water temperature is 78-82°F (25-28°C), with a pH of 6.5-7.5.
  • Tank requirements: A minimum tank size of 55 gallons is recommended for a pair of Angelfish, with an additional 10 gallons for each other fish. To provide enough swimming space, the tank should be at least 36 inches long and 18 inches tall. A tight-fitting lid is essential to prevent Angelfish from jumping out.


  • Habitat: Mollies are found in various coastal and freshwater environments in Central and South America. They are adaptable fish but prefer well-oxygenated water with plenty of open swimming space and some plant cover. Ideal water temperature is 75-82°F (24-28°C), with a pH of 7.0-8.2.
  • Tank requirements: A minimum tank size of 20 gallons is recommended for a small group of mollies, with an additional 5 gallons for each extra fish. The tank should be at least 24 inches long and 12 inches tall. Mollies are strong jumpers, so a tight-fitting lid is necessary.


  • Water parameters: Angelfish and mollies prefer similar water temperatures and pH ranges. This makes them compatible in terms of water parameters.
  • Temperament: Angelfish can be territorial, especially when breeding. They may fin nip slower fish like mollies, especially if the tank is overcrowded or lacks hiding places.
  • Size: Mollies are smaller fish than Angelfish. Larger Angelfish may see smaller mollies as prey. Choose larger, mature mollies if you want to keep them with Angelfish.

Tips for keeping Angelfish and mollies together:

  • Provide plenty of hiding places: live plants, driftwood, and rocks will give both Angelfish and mollies a sense of security and reduce aggression.
  • Maintain good water quality: Regular water changes and proper filtration are essential for the health of all fish.
  • Feed a varied diet: Angelfish and mollies are omnivores and need a diet of high-quality flakes, pellets, and frozen or live food.
  • Start with a small group: Introduce a small group of each species and monitor their behavior. Add more fish gradually if the compatibility is good.
  • Consider a larger tank: A larger tank will provide more space for both Angelfish and mollies and reduce the risk of aggression.

Remember, every fish is an individual, and their behavior can vary. Constantly monitor your fish closely and be prepared to separate them if necessary. Good luck!

molly fish and Angelfish Parameters & Tank Setup

Due to their unique characteristics and behavior, Molly fish and Angelfish have different parameters and tank setup requirements. Molly fish are a tropical species that thrives in water with a temperature range of 72-78°F and a pH level of 7.5-8.5. They prefer a well-planted tank with plenty of hiding spots and open swimming areas.

It’s essential to provide a tank with a minimum of 20 gallons for a small group of mollies to thrive. Additionally, mollies prefer slightly salty water, so adding a small amount of aquarium salt can help replicate their natural habitat and keep them healthy.

On the other hand, Angelfish requires a different tank setup and parameters. They also prefer tropical water with a temperature range of 75-82°F and a pH of 6.8-7.8, but they can be more sensitive to water quality.

Angelfish are also known for their tall and wide body shape, so an elevated tank with a minimum of 20 gallons is recommended to provide enough space to explore and swim. It’s essential to offer a well-filtered tank with regular water changes to maintain good water quality for angelfish.

Additionally, Angelfish are known to be territorial, so providing plenty of hiding spots and visual barriers can help reduce aggression within the tank. Both molly fish and Angelfish require specific tank setups and parameters to thrive in a home aquarium.

What Makes An Ideal Tank Mate For Angelfish?

Finding the perfect tank mates for your Angelfish can be a delightful balancing act! While these majestic fish are generally peaceful, their territorial tendencies and large size require careful consideration when choosing a company for their watery home. Here are some essential qualities to look for in ideal angelfish tank mates:


  • Peacefulness: Top priority! Opt for fish that share Angelfish’s semi-peaceful nature. Avoid aggressive fish or fin-nipping species like barbs, certain cichlids, or boisterous catfish.
  • Size matters: Choose fish that are similar in size or slightly smaller. Tiny fish might be seen as snacks, while much larger fish could intimidate your Angelfish.


  • Compatibility: Consider species that thrive in water parameters similar to angelfish (slightly acidic, warm water 78-82°F). Look for fish that occupy different tank zones: bottom feeders like corydoras catfish or algae eaters like otocinclus catfish leave surface-loving Angelfish undisturbed.
  • Aquascaping: Provide ample hiding spots and swimming space to minimize territorial squabbles. Plants and rocks create natural barriers and enrich the environment for all inhabitants.

Other factors:

  • Diet: Choose fish with different dietary needs to avoid competition for food. Bottom feeders will munch on algae, while Angelfish focuses on flake food or brine shrimp.
  • Schooling behavior: Introduce Angelfish to peaceful schooling fish like neon tetras or rummy nose tetras. Their vibrant movement adds life to the tank and can distract the angels from any territorial urges.

Bonus points:

  • Appearance: Mix and match colors and patterns to create a visually stunning tank! Boesemani rainbowfish or harlequin rasboras add pops of color, while kuhli loaches bring quirky charm with their wriggling antics.
  • Algae control: Consider adding shrimp or snails for natural algae control. Just ensure they’re peaceful varieties like cherry shrimp or mystery snails.

Remember, every Angelfish has its personality. Monitor your tank closely and adjust the mix if necessary. With careful planning and these guidelines, you can create a thriving, harmonious community for your Angelfish to enjoy!
