Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Cichlidae (Cichlids) > Pseudocrenilabrinae
Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  praecox: The species is named in reference to the reproductive precocity of its members (Ref. 52346).

Environment / Climate / Range Ecology

Freshwater; benthopelagic.   Tropical, preferred ?; 5°S - 7°S

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: lower Congo River, below the rapids at Matadi (Ref. 52307, 52346).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm SL male/unsexed; (Ref. 52346)

Short description Morphology | Morphometrics

Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 13-14; Anal soft rays: 7; Vertebrae: 28. Diagnosis: upper lateral line extending the full length of the dorsal fin base and descending a row before proceeding the length of 3 or more scales; 15 gill-rakers along the lower limb of the first arch; 35-37 lateral line scales; relatively large headed and deep bodied; pectoral fin long, usually extending to the level of the spinous anal fin (Ref. 52346).

Biology     Glossary (e.g. epibenthic)

Omnivorous, prefers small organic particles, regardless whether they are plants or small insects (Ref. 52307). Opportunistic bentic microphage; female carries the eggs; probably tolerant of relatively high salinity levels (Ref. 52346).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.6   ±0.27 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (18 of 100) .
