Synodontis congicus is a species of upside-down catfish native to the Democratic Republic of the Congo and the Republic of the Congo where it occurs in the upper and middle Congo Basin.[1] It was first described by Belgian ichthyologist Max Poll in 1971. The first specimen was found near the town of Gangala-na-Bodio, Democratic Republic of the Congo, in the Dungu River.[1][2] The meaning of the specific name "congicus" is "From the Congo".[3]

Description

[edit]

The fish is light grey to silver in color, with one to four spots along the midlateral line of the body.[3]

Like other members of the genus, this fish has a humeral process, which is a bony spike that is attached to a hardened head cap on the fish and can be seen extending beyond the gill opening.[2] The first ray of the dorsal fin and the pectoral fins have a hardened first ray which is serrated.[2] The caudal fin is deeply forked with an extension on the top lobe.[2][3] It has short, cone-shaped teeth in the upper jaw.[2] In the lower jaw, the teeth are s-shaped and movable.[2] The fish has one pair of short maxillary barbels, and two pairs of mandibular barbels that are often branched.[2][3]

This species grows to a length of 16 centimetres (6.3 in) SL although specimens up to 20.2 centimetres (8.0 in) TL have been recorded in nature.[1][2]

In the wild, the species inhabits tropical waters with a temperature range of 22 to 25 °C (72 to 77 °F), a pH of 6.2 – 7.2, and dH range of 5-15.[1] It is found in the Kinsuka rapids in the Lower Congo basin, upstream to the upper Congo basin, excluding the Luapula River and Lake Mweru.[4]
