Family:  Mochokidae (Squeakers or upside-down catfishes), subfamily: Mochokinae
Max. size:  12.4 cm TL (male/unsexed)
Environment:  benthopelagic; freshwater
Distribution:  Africa: Athi and Tana River basins, Kenya (Ref. 52331, 82238, 96595).
Diagnosis:   
Biology:  Oviparous (Ref. 205). Inhabits small streams, main rivers and flooded pools (Ref. 30558). Extremely abundant in ox-bow lakes and river cut-offs in the Lower Tana River (Ref. 39831). Breeding occurs shortly after floods, when ripe fish enter small streams leading to floodwater pools, where they breed; this migration is rather sudden, adult fish migrate in large schools upstream over a period of less than a week (3 to 4 days); one or two additional smaller migrations may occur after the main peak; the stimulus triggering this migration is probably closely connected with rainfall (Ref. 96595).
IUCN Red List Status: Least Concern (LC); Date assessed: 29 June 2022 Ref. (130435)
Threat to humans:  harmless
