Redtail Catfish (Phractocephalus hemioliopterus)
Redtail Catfish (Phractocephalus hemioliopterus)
The Redtail Catfish is one of the most iconic and powerful freshwater predators in the aquarium trade. Instantly recognizable by its massive body, broad head, and vibrant red-orange tail, this species is a true centerpiece fish. Native to the Amazon and Orinoco river basins, Redtails are fast-growing giants best suited for very large aquariums or indoor ponds. This species is recommended for advanced hobbyists due to its size and feeding demands.
Diet
Redtail Catfish are opportunistic carnivores with a massive appetite. Their diet should include:
- Sinking carnivore pellets (staple)
- Fresh or frozen foods (shrimp, fish fillets, worms)
- Occasional whole prey items (tilapia, smelt)
⚠️ Avoid overfeeding and limit live feeder fish, as they can introduce disease and lead to poor nutrition.
Tank Requirements
- Minimum Tank Size: 300+ gallons (juveniles), 1,000+ gallons or pond recommended for adults
- Water Type: Freshwater
- Temperature: 72–80°F
- pH: 6.0–7.5
- Setup: Open swimming space with minimal décor; strong filtration is essential due to heavy bioload
These fish grow extremely fast and require serious long-term planning.
Size
- Current Sale Size: Typically 3–8 inches
Max Size
- Maximum Adult Size: 4–5 feet (48–60 inches)
- Can exceed 100lbs in optimal conditions
Tank Mates
Redtail Catfish will eat anything that fits in their mouth, so tank mates must be chosen carefully:
- Compatible: Large, robust species such as arowanas, stingrays, datnoids, pacu, and large cichlids
- Use caution: Even large tank mates may eventually be eaten or injured
- Avoid: Small to medium fish, slow-moving species
Temperament
Generally calm but highly predatory. Not aggressive in the traditional sense, but extremely opportunistic feeders.
