Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 48635)
Similar to G. filamentosus with the long filament on the dorsal fin but instead of spots, it has bars along the sides (Ref. 48635).
Occurs in shallow inshore coastal waters on sandy bottoms and in estuaries. Maintain discrete, single species' schools (Ref. 13682).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 29.3, mean 28.4 °C (based on 2952 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00520 - 0.01924), b=3.01 (2.85 - 3.17), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±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 to moderate vulnerability (26 of 100) .
