Fisher’s Wood Catfish – Trachelyopterus fisheri

Introduction:
Fisher’s Wood Catfish (Trachelyopterus fisheri) is a distinctive and peaceful species from the slow-moving rivers and streams of South America, notably the Amazon and Orinoco river systems. With its slender, elongated body and unique behavior, it makes a captivating aquarium addition. These catfish grow up to 11 inches (25 cm) in length, and their natural preference for hiding among driftwood and plants makes them an excellent choice for aquariums with ample hiding spots.


1. Natural Habitat and Behavior

In their native environments, Fisher’s Wood Catfish are typically found near submerged wood, branches, and plants in the clear waters of slow-moving rivers. These fish are well-adapted to hiding and foraging among the driftwood, seeking refuge from predators. In an aquarium, they will exhibit similar tendencies, preferring to stay in shaded or dark areas, especially during the day. They are generally peaceful and nocturnal, becoming more active during the nighttime hours when they forage for food.


2. Aquarium Setup

  • Tank Size: A minimum of 30 gallons (115 liters) is recommended for one Fisher’s Wood Catfish. A larger tank is preferable, especially if you plan to keep multiple fish.
  • Substrate: Use a soft, sandy substrate or fine gravel. This allows the catfish to sift through the substrate without injuring its barbels. Avoid sharp-edged materials that could harm their sensitive fins and barbels.
  • Decor: To replicate their natural habitat, include plenty of driftwood, caves, and rocks to provide hiding places. Plants, especially those with broad leaves, will also help create a more natural environment.
  • Water Conditions:
    • Temperature: 74–80°F (23–27°C)
    • pH: 6.5–7.5
    • Hardness: 2–15 dGH
    • Filtration: Moderate filtration is ideal to maintain water quality without creating strong currents. Fisher’s Wood Catfish prefer slow-moving water.
  • Lighting: Low to moderate lighting is recommended, as these catfish are nocturnal and will feel more at ease in dimmer environments.

3. Diet and Feeding

Fisher’s Wood Catfish is omnivorous, enjoying a wide range of foods. In their natural habitat, they feed on detritus, small invertebrates, and plant material. In an aquarium, offer a balanced diet to meet their nutritional needs.

  • Staple Foods: High-quality sinking pellets or wafers designed for bottom-dwelling fish.
  • Supplemental Foods: Offer occasional live or frozen foods such as bloodworms, brine shrimp, or daphnia. You can also feed fresh vegetables like zucchini, cucumber, and spinach.
  • Feeding Tips: Since these catfish are nocturnal, they may prefer to feed at night. To ensure they get enough food, feed them in the evening or when aquarium lights are dimmed. Sinking foods are best to accommodate their bottom-feeding habits.

4. Compatibility with Other Fish

Fisher’s Wood Catfish are peaceful, making them an excellent choice for community aquariums. They can live harmoniously with a variety of other species, including peaceful tetras, other catfish, and various freshwater fish.

  • Tank Mates: Suitable tank mates include peaceful species such as tetras, guppies, peaceful cichlids, and loaches.
  • Avoid: Avoid aggressive fish or those that might nip at the catfish’s delicate barbels.
  • Behavior: They are non-territorial and generally shy, preferring to stay in hiding when not actively foraging. They are unlikely to engage in any aggressive behavior.

5. Common Challenges and Tips

  • Water Quality: Fisher’s Wood Catfish are sensitive to poor water quality. Regular water changes of 25-30% per week are essential to maintain a clean and healthy environment.
  • Barbel Care: The sensitive barbels of this catfish can be damaged by sharp decorations or rough substrate. Ensure that the tank environment is smooth and free of jagged rocks.
  • Night Feeding: Being nocturnal, Fisher’s Wood Catfish may not compete well for food during the day. It’s best to feed them when the aquarium lights are dim or turned off.
  • Hiding Places: These catfish need plenty of hiding spots to feel secure. Include caves, driftwood, and dense plants to replicate their natural environment and help reduce stress.

Conclusion

Fisher’s Wood Catfish (Trachelyopterus fisheri) is a fascinating and peaceful species that makes an excellent addition to a well-maintained community aquarium. They thrive in tanks with plenty of hiding spots, gentle filtration, and a varied diet. With proper care, these catfish can be a long-lasting and unique part of your aquarium, offering a calm and attractive presence.
