Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 9 - 12; Anal spines: 3; Anal soft rays: 7 - 9. Body color silver grey, sometimes with 1-2 randomly positioned black blotches on upper sides and about 10 faint bars. Greatest body depth 2.7 - 3.0 in SL. Similar to S. ogilbyi (Ref. 44894).

Adults occur in small, well-shaded, slow-flowing streams with mixed sand, silt and rock bottoms; also in deeper rocky pools in gorges. Water is typically fresh and clear, between 21° and 28° C, with a neutral or slightly basic pH (Ref. 44894). Eggs are guarded and fanned by the male parent (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01660 (0.00638 - 0.04320), b=2.99 (2.76 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
