About Angelfish and Guppies

Angelfish (Pterophyllum scalare)

  • Appearance: Angelfish are known for their striking appearance. They have a laterally compressed body with elongated triangular fins. Their dorsal and anal fins are lengthy and trailing, giving them an elegant appearance as they move through the water. Their coloration varies widely, from silver and black angelfish to shades of yellow, orange, and even marbled patterns. Some may have vertical black stripes or spots, while others are solid in color.
  • Behavior: Angelfish are generally calm and graceful swimmers. They prefer slow to moderately flowing water and are often found near the middle or top regions of the tank. They tend to form pairs and establish territories within the aquarium. While they are peaceful in nature, they might exhibit some territorial behavior, especially during breeding times.


  • Appearance: Guppies are small, brightly colored freshwater fish. They have a slender, elongated body with a fan-shaped tail fin. What’s fascinating about guppies is the wide variety of colors and patterns they come in. From vibrant reds, blues, greens, and yellows to iridescent and metallic hues, guppies showcase an incredible spectrum of colors. The males typically have more flamboyant and colorful fins, while females are plainer in comparison.
  • Behavior: Guppies are known for their active and lively behavior. They are social fish and thrive in groups. They’re constantly on the move, exploring the aquarium and interacting with each other. Guppies are also known for their breeding habits; they reproduce easily and frequently, so a small group of guppies can quickly populate a tank if not separated by sex.

Both angelfish and guppies are popular choices in the aquarium hobby due to their stunning appearance and relatively easy care requirements. However, it’s crucial to ensure proper tank conditions, including appropriate water parameters and suitable tank mates, to keep these fish healthy and happy.

Can Angelfish and Guppies Live Together?

So, can angelfish and guppies live together in your aquarium? Yes, angelfish and guppies can potentially live together in the same aquarium, but there are considerations to keep in mind due to their differences in size, behavior, and dietary habits.


  • Size Difference: Angelfish are notably larger than guppies, and while adult guppies might be too large to be seen as prey, small guppies, especially fry (baby guppies), can be at risk of being seen as food by angelfish.
  • Aggression: Angelfish, while generally peaceful, can show territorial behavior, especially during breeding times. They might defend their space aggressively if they feel threatened or if they are protecting their eggs.
  • Compatibility with Fry: Angelfish are omnivores and might see guppy fry as a potential snack. Guppy fry are tiny and could be perceived as food, particularly if they are swimming near the surface where angelfish typically patrol.

Strategies for Co-existence

  • Tank Size and Structure: Providing ample space with plenty of hiding spots, plants, or decorations can help guppies, especially fry, evade potential predation by the angelfish. Dense vegetation or floating plants can offer cover for the smaller guppies.
  • Separation: If breeding guppies, consider having a separate breeding tank to protect the fry from potential threats in the main tank. This allows you to raise the fry safely until they grow larger.
  • Observation: Monitor their interactions closely when introducing them. Sometimes, individual fish personalities play a significant role in how they behave towards tank mates.
  • Feeding: Ensure both species are adequately fed to minimize the likelihood of the angelfish viewing smaller guppies as food.

Aquarium Setup

Creating an aquarium suitable for both angelfish and guppies involves careful planning to accommodate the needs of both species, particularly considering the safety of guppy fry. Here’s a guide to setting up an aquarium that suits both:

Tank Size and Setup

  • Size: Aim for a larger tank, ideally 30 gallons (120 liters) or more, to provide ample space for both species. More space helps reduce territorial disputes and allows for better segregation if needed.
  • Plants and Decor: Include dense vegetation, such as floating plants, and tall, bushy plants. Live or artificial plants with broad leaves can serve as hiding spots for guppy fry. Driftwood, caves, or artificial structures can create additional hiding places.
  • Substrate: Use a fine-grain substrate or smooth gravel to ensure the safety of delicate guppy fry.

Water Conditions

  • Temperature: Both species prefer tropical temperatures, but guppies are more adaptable. Aim for a temperature range of 75-82°F (24-28°C).
  • pH and Hardness: Angelfish prefer slightly acidic to neutral water (pH 6.5-7.5), while guppies tolerate a wider range. Aim for a pH between 6.5 and 7.5 with moderate hardness.

Compatibility Considerations

  • Separate Breeding Areas: Create separate areas using dense vegetation or breeding boxes where guppies can give birth away from the angelfish, protecting the fry until they are larger and less vulnerable.
  • Feeding Strategy: Ensure both species are adequately fed. Angelfish may be fed larger pellets or frozen foods, while guppies may require smaller-sized pellets or flakes.

Maintenance and Observation

  • Regular Maintenance: Maintain good water quality with regular water changes and filtration suitable for the tank size.
  • Observation: Keep an eye on their interactions. If aggression is observed, consider rearranging the tank decor to create new territories or providing additional hiding spots.

Introduction and Monitoring

  • Introducing New Fish: Introduce new fish gradually to minimize stress and aggression. Observe their behavior closely during the introduction period.
  • Separate Quarantine: Quarantine new fish before introducing them to the main tank to prevent the spread of diseases.

By setting up the aquarium with consideration for the specific needs and behaviors of both angelfish and guppies, and by providing ample hiding spots and suitable environmental conditions, you can create an environment where both species can coexist relatively harmoniously. Regular monitoring and adjustments based on their interactions will help maintain a peaceful tank environment.
