Etymology: Crenicichla: Latin, crenulatus = cut, clipped + Greek, kichle = wrasse (Ref. 45335). More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 7.0 - ? ; dH range: 10 - ?. Tropical; 25°C - 30°C (Ref. 2059)

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 36377)
Often found in creeks, but sometimes captured in rivers, specially during the dry season. A formidable predator; it consumes essentially aquatic insects, fish and plant material. Not very popular among aquarists because of its aggressive behavior (Ref. 27188).
