Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).
Environment: milieu / Klimaatzone / Diepte / distribution range
Ecologie
; zoet water benthopelagisch; diepte 0 - ? m. Tropical; 15°S - 27°S
Africa: two areas: tributaries of the Phongolo and Komato-Incomati rivers in South Africa and Swaziland (Ref. 7248, 52193), and the Pungwe and middle and lower Zambezi in Zimbabwe (Ref. 7248, 52193).
Grootte / Gewicht / Leeftijd
Maturiteit: Lm ? range ? - ? cm
Max length : 6.5 cm SL mannelijk / geslacht onbekend; (Ref. 52193)
Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 6; Anale stekels: 0; Anale zachte stralen: 11 - 1.
Body shape (shape guide): elongated.
Found in shallow rocky runs and riffles of clear rivers, at an altitude of 900-1200 m above sea level, and depths from 0.2 to 0.4 m (Ref. 52116, 52193). It feeds on invertebrates such as mayfly nymphs and caddis fly, blackfly or midge larvae grazed from rocks (Ref. 52193). Oviparous (Ref. 205). Breeds in summer (Ref. 7248, 52193). Distribution in southern Africa is restricted and may be threatened by alteration of its habitat (Ref. 52116), by water extraction, river regulation and sedimentation (Ref. 52193).
