Actinopteri (ray-finned fishes) > Siluriformes
(Catfishes) > Mochokidae
(Squeakers or upside-down catfishes) > Chiloglanidinae
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 / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical; 23°S - 25°S
Africa: endemic to the Crocodile-Incomati system.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 3 - ? cm
Max length : 6.8 cm SL male/unsexed; (Ref. 3202)
Occurs in rocky rapids and cascades in altitudes of 900-1,200 m. Prefers deeper waters (30-60 cm) over cobbles (Ref. 26172). Feeds on benthic invertebrates such as mayfly and caddis fly nymphs, blackfly and midge larvae and small snails. Oviparous (Ref. 205). Breeds during summer and is a partial spawner. Increasing extraction and regulation of river water as well as pollution threaten this species.
Oviparous (Ref. 205). Distinct pairing during breeding (Ref. 205). Hides eggs in gravel (Ref. 26172).
