Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 19-21; Anal spines: 0; Anal soft rays: 17 - 19; Vertebrae: 32 - 34. This species can be distinguished from Callopanchax monroviae by insertion of first dorsal fin ray slightly anterior to first anal fin ray versus a posterior insertion; it also has a dark red to black postopercular blotch above insertion of pectoral fin (Ref. 84062). Callopanchax sidibei can also be distinguished from males of C. occidentalis and C. toddi by up to three irregular and interrupted horizontal stripes on flanks, an absence of vertical dark red or reddish-brown stripes or broad blotches on sides and a mainly blue to blue-green body colour; females can be distinguished by mid-laterally blue to blue-green coloured scales and the absence of the dark brown vertical stripes or blotches, similar as in males (Ref. 84062).

Habitat of type locality is depression with small water bodies, ditches and connected pools in a secondary forest adjacent to small creek; seems to prefer shaded areas; creeks floods depression during rainy season and provides habitat, fresh water and food for growing juveniles; during dry season pools and ditches dry out, and adults most likely die but can also move into the flowing creek; C. sidibei is an annual species with eggs with prolonged development of 2-9 month (Ref. 84062).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5312 [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): 3.3 ±0.4 se; Based on size and trophs of closest relatives

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

Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .
