Etymology: Placidochromis: Latin, placidus = of peaceful or tranquile appearance + Greek, chromis = a fish, perhaps a perch (Ref. 45335); turneri: Named in honour of Dr. George Turner, who has been working on the ecology, ethology, taxonomy and evolution of Lake Malawi cichlids for almost two decades (Ref. 55898).
Eponymy: George Turner, Bangor University (Wales), has worked extensively on the fishes and fisheries of lakes Malawi and Lalombe. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref. 82804): 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), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
