Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Cichlidae (Cichlids) > Pseudocrenilabrinae
Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); intermedius: Named by Boulenger (1916) presumably in reference to its scale formula which he stated to be intermediate between that of T. jentinki and T. lateralis (Ref. 52346).

Freshwater; benthopelagic; pH range: 6.5 - 7.5; dH range: 2 - ?. Tropical; 24°C - 28°C (Ref. 2059), preferred ?; 14°N - 5°N

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 ±0.3 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (30 of 100) .
