A striking, large African catfish known for its spectacular, fan-like dorsal fin and its ability to produce a 'squeaking' sound when distressed or asserting dominance. While generally peaceful with similarly sized tank mates, it is highly territorial over its chosen cave and will predate on small fish at night.

Available Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Standard (Adult)
The fully mature Featherfin. Features a uniform grey/brown coloration with dark spots and a massive, trailing dorsal fin. Must be housed in a large tank with ample driftwood caves.
Differs in 1 trait from base species
Also known as: Adult, Full Grown
Juvenile (Grow-out)
Juveniles are commonly sold around 2-3 inches and feature a distinct tiger-striped or reticulated pattern that breaks into spots as they mature. They grow very rapidly and will soon require an adult-sized aquarium.
Differs in 4 traits from base species

Featherfin Squeaker Care Guide Summary
The Featherfin Squeaker, scientifically known as Synodontis eupterus, belongs to the Catfish family group. Adults reach a maximum size of approximately 25 cm and have a fusiform body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a high level of biological waste.
To thrive, the Featherfin Squeaker requires a freshwater only aquarium with a minimum volume of 200 litres and a tank length of at least 120 cm. Water temperature should be maintained between 22°C and 27°C, with a pH range of 6.5–8 and a general hardness of 8–20 dGH. A moderate water flow is preferred.
Due to its specialist needs, the Featherfin Squeaker is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard (Adult) and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Featherfin Squeaker Habitat Setup
When setting up an aquarium for the Featherfin Squeaker, a moderate water flow best suits their natural preferences. Because this species occupies the bottom and mid-level zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement.
Featherfin Squeaker Compatibility Notes
Classified as semi-aggressive, the Featherfin Squeaker is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, conspecific aggression can be intense, especially in smaller tanks, and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the bottom and mid-level zones can help reduce competition and territorial overlap.
Featherfin Squeaker Feeding & Diet Considerations
The Featherfin Squeaker is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and is primarily active at dusk and dawn, so offering food shortly after lights-off ensures it receives adequate nutrition.

Similar Species
Striped Raphael Catfish
Platydoras armatulus
A highly robust, armored catfish native to the Amazon and Orinoco basins. Famous for their ability to produce audible squeaking or grunting sounds when distressed or defending territory. They are nocturnal scavengers that spend most of the day hiding in driftwood or caves. Note: Their rigid pectoral spines can easily become tangled in standard aquarium nets.
Cuckoo Catfish
Synodontis multipunctatus
A striking African catfish famous for its 'cuckoo' breeding strategy, where it sneaks its eggs into the clutches of mouthbrooding cichlids. They are highly active, social, and thrive in hard, alkaline water typical of Lake Tanganyika. They must be kept in groups to diffuse conspecific aggression and are best kept with Rift Lake cichlids.
Swordtail
Xiphophorus hellerii
A popular, highly active livebearer known for the male's elongated lower tail fin (the 'sword'). They are hardy but require larger tanks than other common livebearers (like Guppies or Platies) due to their size and immense swimming energy. They require hard, alkaline water and do best with a ratio of one male to multiple females to disperse harassment.
Red-Tail Catfish
Phractocephalus hemioliopterus
A massive, fast-growing predatory catfish from the Amazon basin. Famous for its voracious appetite, bulldozer-like behavior, and distinct red caudal fin. Due to its enormous adult size (often exceeding 4 feet), it is strictly a 'monster fish' that requires a heated indoor pond or a colossal custom aquarium. It is highly predatory and will swallow absolutely any tank mate that can fit into its cavernous mouth.
Clown Knifefish
Chitala ornata
A massive, nocturnal predator native to Southeast Asia, widely known for the distinct row of ocellated spots above its anal fin. While sold as small silvery cute juveniles, they grow incredibly fast into nearly 1-meter giants that require immense aquariums. They are obligate carnivores and will eat any fish small enough to fit in their large mouths. They are shy during the day and require large hiding tubes or caves.
Panda Corydoras
Corydoras panda
A highly popular, peaceful schooling catfish easily identified by its black eye patches and spotted dorsal/tail fins, resembling a giant panda. Native to the cooler waters of the Ucayali river system in Peru, they require slightly lower temperatures than many standard tropical community fish. They are strict bottom-dwellers that sift through the substrate for food.
