Striped Raphael Catfish – Platydoras armatulus

Introduction:
The Striped Raphael Catfish (Platydoras armatulus), also known as the Spotted Raphael Catfish, is a unique and striking species native to the Amazon and Orinoco River basins in South America. This bottom-dwelling catfish is known for its distinctive striped pattern and armored body, which gives it a prehistoric appearance. Typically growing to about 6–8 inches (15–20 cm), it’s a peaceful and hardy species, making it an excellent choice for aquarists seeking a resilient addition to their community tank. Its ability to thrive in a variety of tank conditions and its nocturnal nature make it a great tank mate for other peaceful species.


1. Natural Habitat and Behavior

In its natural habitat, the Striped Raphael Catfish inhabits slow-moving rivers, streams, and flooded forests. It is found in areas with muddy or sandy substrates and dense vegetation.

  • Behavior: Known for its shy and nocturnal behavior, the Striped Raphael Catfish is often seen hiding during the day, coming out at night to forage for food. They are peaceful and will typically avoid other fish, preferring to stay at the bottom of the tank.
  • Appearance: The Striped Raphael Catfish has a tough, armored body with a pattern of dark stripes running across its light-colored body. It has elongated pectoral and dorsal fins, which it uses for both defense and navigation. The catfish is also equipped with sharp spines along its body, particularly around its pectoral fins, which it can use to defend itself from potential predators.

2. Aquarium Setup

  • Tank Size: A minimum tank size of 30 gallons (114 liters) is recommended, though larger tanks are preferable to accommodate this bottom-dwelling species.
  • Substrate: The Striped Raphael Catfish prefers a soft, sandy substrate that allows it to sift through the bottom. Avoid sharp gravel or rocks that could damage its delicate barbels or skin.
  • Decor: This species thrives in a tank with plenty of hiding spots. Use driftwood, rocks, and caves to create a natural environment where the catfish can hide and feel secure. Dense planting, such as Java Fern or Anubias, can provide additional shelter.
  • Water Conditions:
    • Temperature: 74–82°F (23–28°C)
    • pH: 6.0–7.5
    • Hardness: 2–12 dGH
    • Filtration: Strong filtration is essential for maintaining water quality, but avoid powerful currents that could stress the Striped Raphael Catfish. Gentle filtration will ensure the tank remains clean without disturbing this bottom-dweller.
  • Lighting: Striped Raphael Catfish prefer dim or subdued lighting, as they are nocturnal and naturally live in shaded environments. Low to moderate lighting will make the catfish feel more comfortable.

3. Diet and Feeding

The Striped Raphael Catfish is an omnivore and scavenger, feeding on a variety of foods in the wild. It is an opportunistic feeder, consuming both plant matter and small animals.

  • Staple Foods: In the aquarium, they will thrive on high-quality sinking pellets or wafers designed for bottom-feeding fish. Choose pellets with both protein and vegetable content.
  • Supplemental Foods: The Striped Raphael Catfish will also enjoy frozen or live foods, such as bloodworms, brine shrimp, or daphnia. They can also be offered blanched vegetables like zucchini, spinach, or peas.
  • Feeding Tips: Since this catfish is a bottom feeder, make sure that the food reaches the substrate for it to find. Feed small amounts once or twice a day, ensuring no uneaten food remains to pollute the water.

4. Compatibility with Other Fish

The Striped Raphael Catfish is a peaceful, solitary species that gets along with most tankmates.

  • Tank Mates: It is best kept with other peaceful fish that occupy the middle or upper levels of the tank. Good tank mates include tetras, gouramis, cichlids, and other bottom-dwelling species such as Corydoras or loaches.
  • Behavior: While generally shy and non-aggressive, the Striped Raphael Catfish may become territorial if it feels threatened, especially if housed in a tank with aggressive fish. Their armored body and spines also make them less susceptible to harassment, but it is still important to ensure they are not bullied.
  • Avoid: Avoid keeping them with larger, aggressive fish that may see the Striped Raphael Catfish as a target or competition for food.

5. Common Challenges and Tips

  • Nocturnal Behavior: The Striped Raphael Catfish is a nocturnal species, so it is often not active during the day. If you want to observe their behavior, keep the aquarium dimly lit in the evenings.
  • Barbel Care: This species has sensitive barbels around its mouth, which it uses to detect food. Avoid sharp or rough substrates that can injure the barbels.
  • Hiding Needs: Due to their shy nature, the Striped Raphael Catfish requires plenty of hiding spots in the tank. Caves, driftwood, and dense plantings will help it feel secure and comfortable.
  • Water Quality: As a bottom-dwelling species, the Striped Raphael Catfish is sensitive to water quality. Regular water changes (25% per week) and efficient filtration are crucial to keeping the tank clean.
  • Size Considerations: Though not a large species, Striped Raphael Catfish need ample space to feel comfortable. Avoid overcrowding the tank and ensure there is enough space for all inhabitants to thrive.

Conclusion

The Striped Raphael Catfish (Platydoras armatulus) is a hardy and unique species, offering both visual appeal and functional benefits to an aquarium. Its peaceful, nocturnal nature and striking striped pattern make it an attractive addition to community tanks. With proper tank setup, a balanced diet, and the right tank mates, this species will thrive and provide years of enjoyment to aquarium hobbyists.
