African Glass Catfish

Pareutropius debauwi (Boulenger 1900)

Diagnostic Description

provided by Fishbase
Diagnosis: single pair of mandibular barbels; 4-5 (exceptionally 6) branched dorsal fin rays; 30-54 branched anal fin rays; no dark oblique band (from posterior border of operculum to above anus), no dark spots on caudal lobes, dorsal dark band continues onto caudal fin (Ref. 43912, 81643). 7-8 (rarely 9) branchiostegal rays on one side of head; base of anal fin marked by small dark line (Ref. 43912).Description: serrations on inner and outer side of pectoral (Ref. 81643) and dorsal spine (Ref. 43912). 7-9 (rarely 10) branched pectoral fin rays; 36-41 non-fused vertebrae; caudal peduncle in general somewhat longer than deep, sometimes slightly deeper than long; head rounded and rather narrow; snout reaching beyond lower jaw; nasal barbel reaching at least to middle of eye and at maximum to anterior border of operculum; maxillary barbel reaching to posterior border of opercle or beyond; mandibular barbels reaching at least to anterior border of opercle and at maximum to just beyond opercle; no trace of intermandibular barbels (Ref. 43912). Closely related to P. buffei from which it can be distinguished by its peculiar coloration; P. debauwi is also very similar to P. mandevillei but the latter has inner mental barbels which are always absent in P. debauwi (Ref. 43912).Coloration: preserved specimens: broad mid-dorsal line present, continuing on upper half of caudal fin, sometimes somewhat bent downwards near posterior border of fin (Ref. 43912). Lateral line streak continues straight over caudal peduncle (Ref. 43912, 81643), generally slightly bent downwards on caudal fin and sometimes confluent with mid-dorsal line near posterior border of caudal fin (Ref. 43912). No spots on caudal fin lobes; anal fin base with a fine dark band (Ref. 43912, 81643). In life: silvery or whitish with lines grey-blue or grey-black (Ref. 43912, 81643).

Biology

provided by Fishbase
Riverine species with gregarious habits, confined to large as well as moderate and small water systems (Ref. 43912). Forms schools (Ref. 6868). Carnivorous with insectivorous preference; reproduction probably coincides mainly with flood periods (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum total length recorded 148 mm (Ref. 43912, 81643).

Pareutropius debauwi

provided by wikipedia EN

Pareutropius debauwi is a species that belong to the Order Actinopterygii, ray-finned fished, and can be placed in the Schilbeidae family, Schilbid catfishes. This family includes 9 genera and 46 species. The common name for Pareutropius debauwi is the African glass catfish. [2]

Etymology & Taxonomic History

The name of the genus is derived from the Greek words par, eu, and tropis, which respectively translate to "beside or near", "well", and "keel". This is in reference to the families compressed body form. The species name is derived from the Latin work vittatus, which loosely translates to "covered with stripes". This refers to the color and pattern found on this species. [3]

Physical Description

Pareutropius debauwi are silver in color. A single dorsal spine is present with up to six total dorsal soft rays. Seven to eight branchiostegal rays are present on one side of the head. A single pair of mandibular barbels are present. A single mid-lateral band is present across the body. No dark spots on caudal fin lobes but band continues onto caudal fin. The base of the anal fin is marked by a small, dark line. [3]

Distribution & Habitat

River Congo.svg

This species is native to Africa and is spread throughout Angola, the Republic of the Congo, Democratic Republic of the Congo, and Gabon. [4] This species can be found in shallow water systems. Pareutropius debauwi are a freshwater species, specifically found in tropical waters. [5] Pareutropius debauwi are a riverine species that can be found in large and small moderate water systems. [6]

Biology & Behavior

Pareutropius debauwi are omnivores, with some being carnivorous for insects. Mating behavior includes distinct pairing. Reproduction cycles coincide with flood periods. Females tend to be larger than males and have a rounded, short genital papilla. Pareutropius debauwi are an oviparous species. Eggs are unguarded and have no parental care. Are strongly diurnal and are a schooling species. Members within this species can reach up to 15 cm in length. The expected lifespan for this species is around eight years. [7]

Aquarium Life

Pareutropius debauwi should be kept in a large group, with up to at least ten other debauwi. This species is extremely active that requires a spacious environment with dimmed lighting. The water should resemble a moderate current with temperatures between 23°C to 26°C. The species are most comfortable in neutral waters consisting of a pH around 6.5 to 7.5. [8] The diet should consist of a mixture of flakes, granulate and frozen foods. Daphnia, mosquito larvae or brine shrimp are ideal foods. [9] Breeding Pareutropius debauwi in a home aquarium is not recommended but can be done under specific conditions.

Conservation & Threats

Pareutropius debauwi is widespread and faces no serious threats. [10]
