Morphology | Morphometrics
i>Paracanthocobitis nigrolineata can be diagnosed from other congeners by combination of the following characters: incomplete lateral line ending near insertion of dorsal fin; dorsal fin with 9½-10½ branched rays; presence of axillary pelvic lobe; side of body with black stripe ending near caudal fin, usually overlying black lateral blotches extending ventrally from lateral stripe; presence of circular black spot on upper margin of caudal-fin base; black pigment extending from lateral stripe onto pectoral-fin base; absence of marmorated pattern anterior to dorsal-fin origin; black dorsal saddles short, not connecting to lateral blotches; and upper caudal fin with 8 branched (Ref. 117351).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00308 - 0.01417), b=3.01 (2.83 - 3.19), 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 (11 of 100) .
