Featherfin Catfish - Synodontis eupterus : Complete Fish Profile & Care Guide

Introduction

The Featherfin Catfish (Synodontis eupterus) is a distinctive species of freshwater fish belonging to the family Mochokidae. Native to the river basins of Central and West Africa, this species thrives in a diverse range of aquatic environments. Characterized by its unique feather-like dorsal fin and peaceful demeanor, Synodontis eupterus has become a favored species among aquarium enthusiasts. Its adaptability to various water conditions, coupled with its striking appearance, makes it a valuable addition to community aquariums. 

A single Featherfin Catfish can be comfortably housed in an aquarium of at least 200 litres to provide ample swimming space and territory. If you wish to keep a group, you should increase the tank size accordingly to prevent territorial disputes and ensure the well-being of each individual. For a group of 3 to 4 Featherfin Catfish, a tank of at least 500 litres is recommended, depending on the layout and decoration of the aquarium.

The Featherfin Catfish is categorized as a species of moderate difficulty for home aquarium maintenance, primarily due to its relatively large size and the requisite for aquarists to emulate aspects of its natural riverine habitat within the aquarium setting. Attaining lengths of up to 30 cm in captivity, this species is robust-bodied. Coupled with its semi-aggressive demeanour, the Featherfin Catfish may not be an ideal candidate for community aquariums that house smaller, more delicate fish species, or small ornamental shrimp. The combination of its size and temperament necessitates careful consideration of tankmates and environmental structure to ensure a harmonious aquatic ecosystem.

Ideal tank mates for the Featherfin Catfish should be of a peaceful disposition and exceed 5 cm in length to minimize the risk of predation. Suitable companions may encompass Barbs, Gouramis, medium-sized Tetras, Knifefish, Rainbowfish, large Loricariids, or certain resilient West African Cichlid species. However, it is imperative to avoid housing them with Malawi or Tanganyikan Cichlids, due to the latter's aggressive tendencies and the disparate water conditions required by Rift Lake Cichlids.

The aquarium should feature a soft sandy substrate to safeguard the fish's sensitive barbels. An arrangement of bogwood, rocky caves or PVC tubes, and sturdy plants will provide essential shade, while still maintaining an ample open swimming area at the front of the tank. External canister filtration is advised to manage the waste produced by these prolific feeders effectively. To ensure the health of the ecosystem, the water must be well-oxygenated with a moderate flow, and regular partial water changes are essential for controlling nitrate levels. Additionally, heater guards are recommended to protect the catfish from potential burns as they seek out dark, restful crevices.

Aesthetically, the Featherfin Catfish's body exhibits a dark brown hue with a captivating color pattern that evolves with age; the juvenile reticulated markings gradually transition into simpler spots. In maturity, the fish is adorned with isolated small black spots across the back, sides, head, and fins, with the spots on the fins sometimes aligning in rows. Notably, the species' signature high dorsal fin develops pronouncedly over time, the leading rays extending and resembling an ornate fan when fully displayed, adding to its visual appeal.
