How big does the Featherfin Catfish get?

Up to about 30cm, much bigger than the small juveniles sold, so plan your tank around that.

Is the Featherfin Catfish aggressive?

It's semi-aggressive. It shoals in small groups, but each individual defends its own territory, so some squabbling is normal.

Does its appearance change as it grows?

Yes. The body pattern shifts from network-like markings to simple spots, and the dorsal fin becomes more dramatic and feathery with age.

🐟 Featherfin Catfish (Synodontis eupterus)

Dramatic Feathery Dorsal Fin • A Large, Characterful African Catfish • Grows to About 30cm

📋 The Featherfin Catfish, also called the Featherfin Squeaker, is famous for its tall, trailing dorsal fin, which grows more elongated and feathery as the fish matures and fans out in a striking display. Its body pattern transforms with age too, from a network-like reticulated marking as a juvenile into simple spots as an adult. It's a large, characterful African catfish, reaching about 30cm, that makes a rewarding centrepiece for a spacious, well-planned aquarium.

Featherfins are shoaling fish that do best in a small group of three or more, and each individual claims and defends its own territory, so some squabbling is normal. Give each fish its own hiding place. They produce a good amount of waste, so strong filtration matters, and they suit a large, spacious tank better than a small community setup.
