Morphology | Morphometrics
soft rays: 12 - 14;
Vertebrae: 30 - 31. Melanorivulus rubroreticulatus is distinguished from all other members of the M. zygonectes group by its color pattern consisting of caudal fin with broad red bars in males, bars often interconnected to form reticulations and and anal-fin base with short red bars contrasting with intense light blue ground color (Ref. 96663).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00417 (0.00174 - 0.01001), b=3.17 (2.96 - 3.38), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
