Redtail Catfish (Phractocephalus hemioliopterus)

Overview
The Redtail Catfish is one of the most iconic and impressive catfish species in the aquarium hobby. Known for its large size, vibrant coloration, and distinct red tail, this species is a favorite among experienced aquarists who have the space and resources to care for it. Native to the Amazon and Orinoco river basins in South America, the Redtail Catfish is a true monster fish that requires a large, well-maintained aquarium or pond to thrive.

While they are not suitable for most home aquariums due to their size, they make a stunning addition to public aquariums, large ornamental ponds, or fishkeepers with the appropriate setup.

Key Features:

• Scientific Name: Phractocephalus hemioliopterus
• Common Names: Redtail Catfish, Amazon Redtail Catfish
• Place of Origin: Amazon and Orinoco River Basins, South America
• Adult Size: 3-4 feet (in aquariums, up to 6 feet in the wild)
• Lifespan: 15-20 years with proper care

Appearance:
The Redtail Catfish is easily recognizable due to its large size, elongated body, and vivid coloration. Its back is typically dark gray to black, with a lighter, silvery belly. Its most striking feature is its bright red tail, which contrasts beautifully with its dark body. Juveniles may have a more subdued color, but as they mature, the red tail becomes increasingly vivid.

Care Requirements:

1. Tank Size:
   • A minimum of 500 gallons is recommended for a single adult Redtail Catfish. For larger fish or groups, a pond or a custom-built aquarium may be necessary.
   • Note: These fish grow rapidly and need substantial space to swim and thrive.
2. Water Parameters:
   • Temperature: 72-78°F
   • pH: 6.5-7.5
   • Water Hardness: Soft to moderately hard
3. Diet:
   Redtail Catfish are carnivorous and require a protein-rich diet:
   • Large sinking pellets formulated for catfish
   • Live or frozen foods like fish, shrimp, and other meaty offerings
   • Occasional whole fish or beef heart
   • Smaller fish, including tilapia or silversides
4. Tank Setup:
   • Substrate: Smooth gravel or sand is ideal to prevent injury to their sensitive barbels.
   • Decorations: Provide large rocks and driftwood for shelter, but keep in mind that this species requires lots of open swimming space.
   • Filtration: Due to their large size and high waste production, an extremely efficient filtration system is necessary to maintain water quality.

Behavior and Compatibility:
The Redtail Catfish is a solitary and often territorial fish, especially as it matures. They are peaceful toward other fish that do not pose a threat, but they are large and powerful enough to consume smaller fish. Therefore, they are best kept with other large, robust fish species.

Ideal Tank Mates:

• Large, peaceful species like Pacu or Arowanas
• Other large catfish (e.g., RTC x TSN hybrids, Piraiba)
• Larger cichlids or silver dollar fish

Avoid small fish, as they may be seen as prey by the Redtail Catfish.

Special Notes:

• Growth Rate: These fish grow incredibly fast, often reaching 1-2 feet in the first year if provided with proper care.
• Tank Maintenance: Regular and substantial water changes are essential to keep up with the high waste production of this fish.
• Considerations: Due to its large size, the Redtail Catfish is not suitable for most home aquariums. It requires long-term planning and a dedicated setup.
