Redtail Catfish – Phractocephalus hemioliopterus | Majestic large catfish with a bright red caudal fin

The Redtail Catfish (Phractocephalus hemioliopterus) is one of the world's most famous and impressive freshwater catfish. With its contrasting colors, massive build, and intensely red caudal fin, it is a true eye-catcher in large aquariums. This species originates from the Amazon basin and is one of South America's largest freshwater fish.

Young animals, such as the captive-bred specimens offered here, already show the typical pattern of a dark upper side, light underside, and striking, bright red caudal fin. Phractocephalus hemioliopterus is peaceful towards fish of similar size, but due to its eventual size, it can only be permanently kept in very large aquariums or public display tanks.

🍽️ Feeding:

💡 Tip:
Phractocephalus hemioliopterus grows very quickly and requires a very large tank after only a short time. Strong filtration, regular water changes, and plenty of space are mandatory. Best kept individually or with robust large fish.
