Synodontis velifer

Adults of this fish can reach up to 23 cm in length. A distinctive feature is the robust protection of the head, formed by bony plates that create a helmet-like structure and are densely covered with small spines. The dorsal and pectoral fins are particularly large, with their first rays transformed into sharp spines. The other fins are significantly smaller. The tail of the fish is massive and forked. The body coloration is gray, with a characteristic pattern of dark, round spots. Several pairs of sensitive barbels are located around the mouth, which help the Synodontis navigate and find food on the silty bottom in murky water.

The species inhabits river basins in West Africa, including the Pra, Volta, Sassandra, and Bandama rivers in Ghana, Côte d'Ivoire, Togo, and Burkina Faso. It populates water bodies with sandy-gravel bottoms and moderate currents. In nature, it prefers biotopes with soft water and the presence of natural shelters, such as snags and stones, where it leads a predominantly nocturnal lifestyle.

This fish is distinguished by its peaceful and calm disposition. It coexists well with its own kind and with other non-aggressive species. It prefers a secretive lifestyle, showing activity mainly at night. During the day, Synodontis velifer usually hides in shelters.

For the comfortable keeping of one or two Synodontis velifer catfish, an aquarium of at least 200 liters will be required. In the aquarium's setup, it is vitally important to provide a sufficient number of shelters, such as caves, where the fish can hide during the day. These refuges can be created from piles of stones, forming grottoes and crevices, or by using snags and plant thickets, placing the latter in front of the entrance to the shelter. Aquarium lighting can be any, especially if shelters are present and other fish species are kept; its intensity should primarily be determined by the needs of the plants. The species originates from swampy regions, so the water in the aquarium should have low pH and GH values. The presence of dissolved tannins, which naturally form from the decomposition of natural leaves, snags, and tree bark, will be beneficial. Aquarium maintenance should follow a standard schedule, including weekly partial water changes, removal of organic waste (e.g., food remnants and excrement), and regular equipment prophylaxis.

The diet of these fish should consist of high-protein foods, and the products must be sinking. Good options include dry, live, or frozen bloodworms, earthworms, tubifex, as well as various dry foods presented as flakes and granules.

The fish are oviparous. During the spawning period, pair formation is observed. Given their secretive lifestyle and specific environmental requirements, breeding in home aquariums is difficult and requires stimulation. Detailed data on the natural reproductive cycle in captivity are limited; hormonal stimulation methods are most often used to obtain offspring.

The species has a strong immune system when kept under proper conditions but is sensitive to sudden changes in water parameters and high levels of organic waste. Characteristic problems include bacterial infections of the skin and fins, which arise from poor filtration. Prevention involves weekly partial water changes and maintaining substrate cleanliness.

When choosing, attention should be paid to the integrity of the fins and the absence of damage on the body, as catfish are prone to injuries during transportation. A healthy individual should be active during twilight hours, have clear eyes, and a distinct pattern on its body. Avoid fish with signs of emaciation, sunken bellies, or film on the skin.
