Red Devil Angelfish

Red Devil Angelfish

The Red Devil Angelfish (*Pterophyllum scalare*) is a strikingly beautiful freshwater fish that is known for its vibrant red hues and elegant, flowing fins. A variation of the popular angelfish, the Red Devil Angelfish stands out with its bright coloration, making it a stunning addition to aquariums. This fish is particularly appreciated for its graceful swimming style and unique appearance.

Physical Characteristics:

• Size: Red Devil Angelfish typically grow to about 15-20 cm (6-8 inches) in length, including their fins.
• Coloration: The Red Devil Angelfish features a stunning combination of deep red and orange hues, with the intensity of the colour increasing in well-maintained tanks. The body of the fish is generally a light to medium red, while the fins may range from red to orange, giving it a fiery, devilish look.
• Fins: Like other angelfish, the Red Devil has long, flowing fins, particularly the pectoral fins and dorsal fin. These fins give the fish its graceful, angelic appearance as it moves through the water.
• Shape: The body of the Red Devil Angelfish is diamond-shaped, which is typical for angelfish species. The long fins and overall shape contribute to the species’ elegant profile.

Behavior:

• Temperament: The Red Devil Angelfish is known for its more assertive and territorial nature compared to other angelfish varieties. It can be quite aggressive, especially during breeding, and may not be the best choice for a community tank with smaller or more docile species.
• Activity Level: These fish are moderately active, often found swimming in the mid-to-upper levels of the tank. They tend to explore their environment and will often display their fins in full flare to assert dominance.
• Community Behavior: While they are relatively peaceful when not breeding, the Red Devil Angelfish can become territorial and aggressive, especially toward other angelfish or similarly sized species. It is best to house them with other larger, more robust fish that can hold their own in the tank.

Aquarium Care:

• Tank Size: A minimum tank size of 75 liters (20 gallons) is recommended for a single Red Devil Angelfish. However, larger tanks (100 liters or more) are ideal, especially if housing multiple fish or creating a community tank.
• Water Parameters:
  • Temperature: Red Devil Angelfish thrive in warm water, with an ideal temperature range of 24°C to 30°C (75°F to 86°F).
  • pH: They prefer slightly acidic to neutral water, with a pH range of 6.0 to 7.5.
  • Hardness: Soft to moderately hard water, with a general hardness (GH) of 3-10 dGH, is ideal.
• Tank Setup:
  • Substrate and Decorations: A soft, sandy substrate is best for the Red Devil Angelfish. They appreciate a tank with plenty of hiding spots created by rocks, driftwood, and live plants. Adding plants such as Java Fern or Amazon Sword provides cover and mimics their natural environment.
  • Lighting: Moderate lighting is recommended to allow the fish's beautiful colouration to shine. Floating plants or plants in the background can help create shaded areas for the fish to feel secure.
  • Filtration: A good filtration system is crucial to maintain clean water, as Red Devil Angelfish require high water quality. A sponge filter or a low-flow filter can be used to maintain a gentle current that won’t stress the fish. Regular water changes (about 20-30% weekly) are essential.

Diet:

The Red Devil Angelfish is omnivorous and should be fed a balanced diet to keep them healthy and vibrant. Their diet should include:

• Pellets: High-quality cichlid-specific pellets should form the staple of their diet. These pellets are designed to meet their nutritional needs.
• Live or Frozen Foods: Offer live or frozen foods such as brine shrimp, bloodworms, and daphnia to provide essential protein and variety.
• Vegetable Matter: Including blanched vegetables such as spinach, peas, or zucchini can help provide a balanced diet and ensure proper digestion.

Tankmates:

Due to their territorial nature, it is important to choose tankmates for the Red Devil Angelfish carefully. Suitable tankmates include:

• Large, Peaceful Fish: Species like larger cichlids (e.g., Green Terror, Oscar), or peaceful catfish such as Corydoras can make good companions.
• Robust Fish: Fish that are not overly aggressive but can hold their own, such as larger barbs or rainbowfish, may also work well.

Avoid housing Red Devil Angelfish with smaller fish, or those that nip at fins, as this can cause stress and aggression.

Breeding:

Breeding Red Devil Angelfish can be a rewarding experience with proper setup:

• Breeding Setup: A separate breeding tank with soft, slightly acidic water (pH 6.0-7.0) is recommended. The water temperature should be kept between 28°C and 30°C (82°F-86°F).
• Spawning Behavior: The female will lay her eggs on flat surfaces such as rocks or the sides of the tank, and the male will fertilise them. Both parents will guard the eggs and protect the fry once they hatch.
• Fry Care: Once the fry are free-swimming, the parents can be removed to prevent them from eating their young. The fry can be fed with infusoria or newly hatched brine shrimp until they are large enough to eat regular foods.

Special Considerations:

• Territorial Nature: Red Devil Angelfish can be very territorial, especially during breeding. Providing plenty of space and hiding spots is key to reducing stress and aggression.
• Water Quality: Regular monitoring of water quality is essential for the health of the fish, as they are sensitive to poor water conditions.
