Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).
More on author: Boulenger.
Issue
Somewhat mysterious species in that several undetermined Chiloglanis populations from East and Central as well as South Africa have been assigned to this species, although it is only inadequately known (Ref. 78218).
Environment: milieu / climate zone / depth range / distribution range
Ökologie
; süßwasser benthopelagisch; pH range: 6.0 - 7.5; dH range: ? - 15. Tropical; 20°C - 26°C (Ref. 2059); 10°S - 19°S
Africa: Limpopo River system, Cunene, Kafue, Zambezi (above and below Victoria Falls), Okavango, Lake Malawi and Lake Kariba (Ref. 3202, 52193). Presence in the upper Congo River basin in Zambia (Ref. 3202) is unconfirmed (Ref. 52193) and questionable. Also reported from the Pungwe and Buzi systems and east coast rivers in Tanzania (Ref. 7248, 52193). Several undetermined Chiloglanis populations from East and Central as well as South Africa have been assigned to this species, although it is only inadequately known; also Rufiji/Ruaha specimens are not conspecific (Ref. 78218).
Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 6.5 cm SL Männchen/unbestimmt; (Ref. 52193)

Common in the cool waters of mountain streams (Ref. 5595); found.in rocky riffles and rapids as well as pools (Ref. 52193). It feeds on the biocover of rocks and grazes on algae (Ref. 5595). Oviparous (Ref. 205).
