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
Ecology
Freshwater; demersal. Tropical; 24°C - 28°C (Ref. 13614); 13°S - 20°S
Africa: northwestern Madagascar (Ref. 78623).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 15.9 cm SL male/unsexed; (Ref. 78623)
Dorsal spines (total): 18 - 20; Dorsal soft rays (total): 13 - 15; Anal spines: 9 - 11; Anal soft rays: 11 - 12. Diagnosis: A shallow-bodied Paretroplus distinguished from all congeners except P. gymnopreopercularis by the presence of a blotchy, mottled, and irregular pigmentation pattern, the absence of vertical bars on the flanks, and by a fleshy snout that extends rostral to the lips and also ventrally to cover a portion of the upper lip (Ref. 78623). Paretroplus kieneri is distinguished from its sister taxon, P. gymnopreopercularis, by the presence of a more or less fully scaled preopercle, except along the ventral margin, vs. completely asquamate; a pointed and mildly convex predorsal profile, vs. blunt and strongly convex; and a second lacrimal plate that forms a part, albeit small, of the orbit margin, vs. second lacrimal plate excluded from orbit margin; the pigmentation pattern of P. kieneri is conspicuously blotchy, mottled, and irregular, whereas P. gymnopreopercularis is characterized by a weakly mottled and especially uniform chain-link lateral pigmentation pattern, owing to darkly pigmented scale margins (Ref. 78623).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01698 (0.00667 - 0.04322), b=2.96 (2.74 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 2.8 ±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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
