🐟 Redtail Catfish (Phractocephalus hemioliopterus)
Iconic Amazonian Giant • Bold Red Tail • A Pond and Public-Aquarium Showpiece
📋 The Redtail Catfish is one of the most iconic Amazonian giants, with a bold red tail, a broad head, and a powerful body, native to the Amazon, Orinoco, and Essequibo basins. It's sold as a small juvenile and it's one of the fastest-growing freshwater fish in the trade, commonly gaining 1-2 inches a month in its first year and often passing 60cm within twelve months. Adults reach about 100-130cm, and can grow to as much as 180cm and 80kg, which makes it a showpiece for large indoor or outdoor ponds and public-aquarium-scale systems.
Redtails are bold, characterful predators that will eat anything that fits in their mouth, and they're peaceful toward fish too large to swallow. Room is what keeps a Redtail healthy and growing well, since cramped spaces can stunt growth and shorten its life. With good care it lives 15-20 years or more, so it's a long-term companion. Commercial stock is farmed in very large ponds, and the species isn't bred in home aquariums.
