Maturity: Lm ?  range ? - ? cm
Max length : 90.0 cm TL male/unsexed; (Ref. 11344); common length : 36.0 cm TL male/unsexed; (Ref. 12193); max. published weight: 7.5 kg (Ref. 11344)
Adults occur in fresh water, often well inland. Inhabits larger free flowing clear water streams (Ref. 11225). They lie mostly on the bottom in slower moving part of streams, sometimes on logs or large stones and on leaf debris or gravel (Ref. 11225). A carnivorous and benthic fish that relies on its sluggish behavior and cryptic coloration (Ref. 36880). Feeds on all greater invertebrates and regularly also fish (Ref. 92840).
