Issue
Junior synonym Tigrigobius inornatus is considered a valid species by some authors (see van Tassell 2011, Ref. 89468 for other works). Please send references or more studies are needed.

Marine; reef-associated; depth range ? - 21 m (Ref. 87125), usually ? - 15 m (Ref. 87125). Tropical
Eastern Central Pacific: Gulf of California to Colombia.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 3.2 cm SL male/unsexed; (Ref. 11482)
Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 9 - 11; Anal spines: 1; Anal soft rays: 8 - 10. Distinguished by the following characters: head plump, more or less rounded, dorsoventrally compressed; mouth slightly oblique, forming an angle of about 20° to 25° with body axis; maxilla extending under middle to rear margin of eye, occasionally only to front of pupil; profile of snout steeply rounded in lateral view; interorbital narrow equal to or less than one-half eye length; gill-rakers on outer face of first arch short and slender; those on second and following arches shorter; mandibular frenum without lobes; anterior nostril a short tube, posterior nostril with a raised rim; most males with first, rarely second, first dorsal-fin spines filamentous, the first reaching to last first dorsal-fin spine base to second ray base of second dorsal fin, and occasionally to the ninth dorsal-fin ray base; scales absent (Ref. 87125).
Inhabits coral and rocky reefs (Ref. 11482). Mobile-invertebrate feeder (Ref. 57615). Picks ectoparasites from other fishes.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00491 - 0.01692), b=3.15 (3.00 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
