Etymology: Congolapia: Congolapia is a contraction of the words Congo and Tilapia; all species of Congolapia are only known from the central Congo basin.. More on author: Pellegrin.

soft rays: 8 - 9. Diagnosis: Congolapia bilineata differs from C. crassa and C. louna by having one complete scale row and one additional scale row with smaller dorso-ventrally compressed scales between the upper lateral line and the base of the last dorsal spine vs. two complete scale rows and one additional row of very small scales in-between (Ref. 92878). Further, C. bilineata differs from C. crassa by a shallower body with only a minimal overlap, 32.2-40.5% of standard length vs. 40.4-48.4%; and from C. louna by a shorter last dorsal spine, 9.4-12.2% of standard length vs. 12.9-15.0% (Ref. 92878). All scales cycloid; 26-27 scales on horizontal line; 17-22 upper lateral line scales; 8-11 lower lateral line scales (Ref. 92878).
Colour: Background colourlight olive-green to yellowish, chest and belly light yellow to whitish with small reddish dots; lower half of head yellowish olive, especially on cheek, and upper half of head olive-green; upper lip bluish and lower lip whitish; a horizontal iridescent blue line above anterorostral margin of preopercle; iris dark brown (Ref. 92878). Apparently depending on motivational state, body with six or seven black backward slanted, unbranched (not Y-shaped) bars and a nape band or two black stripes along the lateral line; a yellow line between these two lines; black thin lachrymal stripe extending from lachrymal to jaw angle; black opercular spot, extended into a sloping stripe (Ref. 92878). Pectoral fin light greenish to hyaline with a yellow base, pelvic fin and anal fin greenish yellow; dorsal fin greenish, yellow edged, no clear 'tilapia spot', except for juveniles; caudal fin greenish yellow (Ref. 92878).
Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri
Africa: the central Congo basin in the western Cuvette Centrale and central Cuvette Centrale, including Alima River, Lefini River, lower Sangha River, Ruki River and Maringa River (Ref. 55074, 74387, 92878).
Congolapia bilineata is found in grass-bank as well as forest-bank habitats, and this during the dry as well as wet season (Ref. 92878).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (-0.16711 - 0.17489), b=3.12 (3.03 - 3.21), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278): 2.3 ±0.0 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 vulnerability (22 of 100) .
