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 - ?; depth range - m (Ref. ), usually - m (Ref. ). 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).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00782 - 0.02438), b=3.05 (2.89 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.49 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
