Marble Angelfish Care Guide: Tank Setup, Breeding, Disease Prevention and More…

A Marble Angelfish is a popular freshwater aquarium fish known for its striking appearance. This species belongs to the Cichlidae family and is a variant of the common angelfish (Pterophyllum scalare). The marble pattern on their bodies sets them apart, featuring a mix of dark and light colors resembling the intricate swirls of a marble. This distinctive pattern can vary greatly among individual fish, making each one unique.

In terms of care, Marble Angelfish require a well-maintained tank with suitable water conditions, including a slightly acidic to neutral pH and warm temperatures. They are generally peaceful but can exhibit territorial behavior during breeding. Providing a balanced diet and maintaining good water quality are crucial for their well-being. If you’re considering adding Marble Angelfish to your aquarium, it’s important to research and ensure you meet their specific requirements for a thriving and visually appealing aquatic environment.

Key Characteristics

Appearance: Marble Angelfish are known for their distinctive marble-like pattern on their bodies, featuring a mix of dark and light colors. The pattern can vary significantly, making each fish unique. They have a laterally compressed body, long fins, and a graceful swimming motion.

Size: Typically, Marble Angelfish can reach a size of 6 to 8 inches (15 to 20 cm) when fully grown. The size may vary slightly depending on factors like genetics and environmental conditions.

Lifespan: With proper care, Marble Angelfish can have a lifespan of 3 to 5 years in captivity. Providing a suitable environment, a balanced diet, and prompt medical attention when needed contribute to their longevity.

Water Parameters:

  • pH Level: 6.0 to 7.5
  • Temperature: 75 to 82 degrees Fahrenheit (24 to 28 degrees Celsius)
  • Hardness: 3 to 8 dGH (degrees General Hardness)

Maintaining stable water conditions is crucial for the health of Marble Angelfish, and regular water testing is recommended.

Diet: Marble Angelfish are omnivores. Their diet should include a variety of high-quality flakes, pellets, and live or frozen foods such as brine shrimp, bloodworms, and small insects. Providing a balanced and nutritious diet is essential for their overall well-being.

Origin: The natural habitat of angelfish, including the Marble Angelfish, is the Amazon River basin in South America. They are found in slow-moving waters, tributaries, and flooded areas with vegetation.

Behavior: Marble Angelfish are generally peaceful but can exhibit territorial behavior, especially during breeding. They are best kept in groups or pairs in a sufficiently spacious tank with suitable hiding places.

Tank Requirements:

  • A tank of at least 20 gallons is recommended for a pair of Marble Angelfish.
  • Provide ample hiding spots and vertical space as they like to swim in different levels of the tank.
  • Decorate the tank with live or artificial plants to mimic their natural environment.

Marble Angelfish Care Guide

Tank Setup:

  1. Tank Size: Provide a tank of at least 20 gallons for a pair of Marble Angelfish. Larger tanks are preferable for multiple angelfish.
  2. Water Parameters:
    • pH Level: 6.0 to 7.5
    • Temperature: 75 to 82 degrees Fahrenheit (24 to 28 degrees Celsius)
    • Hardness: 3 to 8 dGH (degrees General Hardness)
  3. Filtration: Use a reliable filtration system to maintain water quality. Angelfish are sensitive to changes in water parameters, so regular water testing and changes are essential.
  4. Decorations: Include hiding spots and vertical structures in the tank. Angelfish enjoy swimming in different levels, so provide tall plants, driftwood, and rocks.
  5. Substrate: Use a soft substrate to mimic their natural environment. Sand or rounded gravel is suitable, as angelfish may sift through the substrate.


  1. Diet: Marble Angelfish are omnivores. Offer a balanced diet that includes high-quality flakes and pellets. Supplement their diet with live or frozen foods like brine shrimp, bloodworms, and small insects.
  2. Feeding Frequency: Feed them 2-3 times a day, providing only the amount they can consume in a few minutes. Overfeeding can lead to health issues and water quality problems.

Behavior and Compatibility:

  1. Tankmates: Marble Angelfish are generally peaceful, but they can become territorial during breeding. Compatible tankmates include other peaceful community fish. Avoid aggressive or fin-nipping species.
  2. Social Structure: They can be kept in pairs or small groups. If keeping multiple angelfish, provide adequate space and hiding spots to reduce aggression. like silver angelfish

Disease Prevention:

  1. Quarantine New Fish: Always quarantine new fish before introducing them to your main tank to prevent the spread of diseases.
  2. Water Quality: Maintain stable water parameters and perform regular water changes to keep the tank environment clean.
  3. Observation: Monitor your angelfish regularly for any signs of illness, such as changes in behavior, appearance, or appetite.
  4. Isolation: If you notice any sick fish, isolate them promptly to prevent the spread of disease to other tank inhabitants.
  5. Proper Nutrition: A well-balanced diet enhances the immune system. Ensure your angelfish receive nutritionally complete food to promote overall health.

Common Diseases:

  1. Ich (White Spot Disease): Caused by a parasite, Ich is characterized by white spots on the fish’s body and fins.
  2. Fin Rot: Bacterial infection leading to frayed or decaying fins.
  3. Skin and Gill Flukes: Parasitic infections affecting the skin and gills.


  1. Medication: Use appropriate medications for specific diseases. Follow instructions carefully.
  2. Isolation: Move sick fish to a quarantine tank to prevent the spread of the disease.
  3. Increased Temperature: Raising the tank temperature slightly can speed up the life cycle of some parasites.

Regular observation, preventive measures, and a well-maintained environment contribute to the overall health and longevity of Marble Angelfish in your aquarium.

Marble Angelfish Breeding Guide

Breeding Marble Angelfish can be a rewarding but intricate process. Here’s a guide on how to breed them successfully:

1. Selecting Breeding Pairs:

  • Choose healthy and mature angelfish. Look for individuals with vibrant colors and well-formed bodies.
  • A proven breeding pair or a group of young angelfish that will pair off as they mature is ideal.

2. Setting Up the Breeding Tank:

  • Use a separate breeding tank with a capacity of at least 20 gallons.
  • Maintain optimal water conditions: pH 6.5 to 7.0, temperature around 80 degrees Fahrenheit (27 degrees Celsius), and soft to slightly hard water.
  • Provide a flat surface for the angelfish to lay eggs. A vertical slate, a smooth rock, or a piece of slate leaned against the tank’s side can serve as a suitable spawning site.
  • Include fine-leaved plants like Java moss for the eggs to adhere to.

3. Conditioning:

  • Feed the breeding pair a varied and nutritious diet to condition them for breeding. Include live or frozen foods like brine shrimp and bloodworms.
  • Conditioning can take several weeks to a month.

4. Introducing the Breeding Pair:

  • Once the angelfish are conditioned, introduce the pair into the breeding tank.
  • Monitor their behavior. The pair will likely display courtship rituals, such as swimming together and cleaning a chosen spawning site.

5. Spawning:

  • The female will lay eggs on the chosen surface, and the male will fertilize them.
  • After spawning, the parents will guard the eggs. Be cautious not to disturb them during this time.

6. Egg Care:

  • The parents may fan the eggs to provide oxygen and guard against potential threats.
  • If the parents show signs of eating the eggs, it might be necessary to remove them and place the eggs in a separate container with similar water parameters.

7. Hatching Fry:

  • After a few days, the eggs will hatch into fry. The fry will initially feed off their yolk sacs.
  • Once the yolk sacs are absorbed, start feeding the fry with infusoria, powdered fry food, or newly hatched brine shrimp.

8. Rearing the Fry:

  • Keep the fry in a separate tank to protect them from larger fish.
  • Gradually introduce larger food as the fry grow. Crushed flakes, micro worms, and baby brine shrimp are suitable options.

9. Water Changes:

  • Regular water changes are crucial for the health of both the fry and the breeding pair.

10. Patience and Observation:

  • Breeding angelfish requires patience. It may take several breeding attempts for a pair to produce viable fry.
  • Observe the behavior of the parents and the fry regularly to ensure their well-being.

Successful breeding of Marble Angelfish often involves some trial and error, so be prepared to learn and adapt based on the behavior of your specific fish.
