Ever seen a catfish swim upside down? Meet the Featherfin Catfish (Synodontis eupterus), a quirky character that adds a touch of the unusual to any aquarium. These captivating creatures, sometimes called “squeakers,” boast eye-catching feathery fins and a peculiar upside-down swimming habit. This comprehensive guide delves into every aspect of Featherfin Catfish care, from tank setup and diet to tank mate compatibility and the challenges of breeding. Whether you’re a seasoned aquarist or just starting out, this guide will equip you with the knowledge to ensure your Featherfin Catfish thrives.
The Featherfin Catfish, also known as the Featherfin Squeaker or Lace Cat, hails from the rivers and lakes of Central and West Africa. Easily identified by its prominent feathery dorsal fin and three pairs of sensory barbels, this intriguing species is a guaranteed conversation starter. Their tendency to swim upside down adds to their unique charm, while their ability to produce squeaking sounds by rubbing their pectoral fin spines against their bodies is a fascinating quirk. This squeaking likely serves as both a defense mechanism and a means of communication. Young Featherfin Catfish sport striking zebra-like stripes, which gradually transition to black spots as they mature. While they can reach nearly a foot long in the wild, they typically grow to a more manageable 6-8 inches in home aquariums, occasionally reaching up to 10 inches with exceptional care.
Setting Up the Perfect Home
Providing a spacious and stimulating environment is crucial for the well-being of your Featherfin Catfish. A 50-gallon tank is the absolute minimum for a single fish, with larger tanks (200 liters for one, 500 liters for a small group) strongly recommended, especially for multiple catfish. These active fish need room to explore!
Choose a soft sand or smooth gravel substrate to protect their sensitive barbels. Incorporate plenty of hiding places using driftwood, rocks, caves, or even PVC pipes. This mimics their natural habitat and reduces stress. Featherfin Catfish prefer dimly lit environments, so avoid overly bright aquarium lights.
Given their substantial waste production, maintaining excellent water quality is paramount. Invest in a high-quality filter (a canister filter is a good choice) and perform regular partial water changes to keep nitrate levels in check. Aim for the following water parameters:
Parameter
Ideal Range
Temperature
71-78°F (22-26°C)
pH
5.6-7.5
Water Flow
Moderate, well-oxygenated
Feeding Your Featherfin
Featherfin Catfish are omnivores with a hearty appetite. Sinking omnivore tablets form a good base for their diet, supplemented with treats like bloodworms, insect larvae, algae wafers, brine shrimp, and even small pieces of vegetables like cucumber. Daily feedings are usually sufficient. As a bonus, they often consume pesky snails, contributing to a cleaner tank, and generally leave live plants undisturbed.
Choosing Compatible Tank Mates
While generally peaceful, Featherfin Catfish can be territorial, especially towards their own kind. Choose tank mates carefully. Larger, non-aggressive species are ideal. Good choices include certain Barbs, Gouramis, Tetras, Knifefish, Rainbowfish, larger Loricariids (like some Pleco species), and compatible West African Cichlids. Avoid small, bottom-dwelling fish like Otocinclus or Bristlenose Plecos, as they could be seen as prey. Highly aggressive species, like Malawi or Tanganyikan Cichlids, are also incompatible. If keeping multiple Featherfin Catfish, ensure a spacious tank with numerous hiding places to minimize territorial disputes.
Breeding Challenges
Breeding Featherfin Catfish in home aquariums is notoriously difficult, with most successes occurring in commercial settings using hormone injections. They are egg scatterers in the wild, exhibiting no parental care. Females are typically plumper than males, especially when carrying eggs. While home breeding is a significant challenge, understanding their natural breeding habits can be insightful.
Ensuring a Long and Healthy Life
With proper care, Featherfin Catfish can live for 8-10 years, with some anecdotal reports suggesting a lifespan of up to 25 years. A stimulating environment with varied decor, low lighting, and compatible tank mates is key to their longevity. Managing their territorial tendencies through thoughtful tank design, incorporating hiding spots and visual barriers, is essential for their well-being.
Delving into Aggression
Featherfin Catfish are sometimes labeled “semi-aggressive.” They’re not inherently vicious, but they are territorial, especially towards smaller, bottom-dwelling fish. Adequate tank size (50 gallons minimum, larger is better), ample hiding places (caves, driftwood, plants), and a soft substrate are crucial for minimizing aggression. Choosing the right tank mates is also key. Avoid tiny bottom-dwellers, opting instead for mid-water or top-dwelling species like tetras, danios, gouramis, or some larger, compatible African cichlids.
Multiple featherfins can cohabitate in a very large tank with plenty of hiding spots. Maintaining pristine water conditions and providing a varied, nutritious diet also reduces stress and aggression. Their squeaking sounds can be a warning sign, while their upside-down swimming is simply a quirky behavior.
In the wild, Featherfin Catfish can reach an impressive 12-14 inches, sometimes even 18 inches. However, in aquariums, they typically grow to 6-8 inches, rarely exceeding 10 inches. Factors influencing their size include genetics, diet, tank size, and water quality. A 50-gallon tank is the minimum recommended size. Their sensitive barbels necessitate a soft sand or smooth gravel substrate.

Ideal Tank Mates for Featherfin Catfish
Choosing suitable tank mates for Featherfin Catfish requires careful consideration. Their semi-aggressive nature and territoriality mean smaller, bottom-dwelling fish are at risk. A large tank (50 gallons minimum) with ample hiding places is essential. Compatible tank mates include mid-water and top-dwelling fish like certain African and New World cichlids, rosy barbs, rainbowfish, and potentially Horseface Loaches in a much larger aquarium (90+ gallons). Avoid small tetras, small catfish, and ornamental shrimp. A varied, protein-rich diet keeps the featherfin satiated, reducing the likelihood of preying on tank mates.
