Etymology: Paretroplus: Name from the Greek 'para' meaning 'on the side of'; in taxonomy it is commonly used in generic names to express similarity or relatedness; in the present case it would mean 'next to Etroplus' (S.Kullander, pers.comm. 3/11)..
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 13°S - 20°S
Africa: northwest Madagascar (Ref. 5675) in Betsiboka River drainage (Ref. 78623).

(total): 15 - 18;
soft rays: 13 - 16. Diagnosis: A member of the deep-bodied clade of Paretroplus and distinguished from all congeners by the presence of a large and essentially square to rounded solid black pectoral patch, located above and slightly posterior to the pectoral-fin base, and generally not extending dorsal to the upper branch of the lateral line (Ref. 78623).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01698 (0.00670 - 0.04303), b=2.96 (2.75 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.3 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.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
