Morphology | Morphometrics
soft rays: 8 - 10;
Vertebrae: 25 - 26. First dorsal fin distally rounded without filamentous spines. Posterior margin of caudal fin rounded. Scales small, 39-55 scales in a longitudinal row and 19-25 scales in transverse row. Color of specimens before fixation: nuchal crest with transversely alternating reddish-brown and light greenish-brown areas; body light greenish brown reticulated with brown on upper anterior part and having iridescent bluish or greenish spots surrounded by reticulation; first dorsal fin with red upper margin, submarginal row of contiguous yellow spots, grayish-red band on middle part, greenish gray on lower part, and large blackish spot with blue spots between fifth spine and fin terminus; second dorsal fin red with two or three irregular longitudinal yellow stripes on middle part, and greenish gray on basal part; anal fin proximally red and distally dark gray; pectoral fin with a red area on middle to lower part (Ref. 49948).
Inhabits mangrove streams with mud or sand bottoms (Ref. 49948).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.2 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 (15 of 100) .
