Maturity: L_m ? range ? - ? cm
Max length : 14.2 cm SL jantan/; (Ref. 36713)

The most ubiquitous, frequently occurring and abundant species of this genus. Occurs in all kinds of streams where the substrate is rocky and the water is flowing (Ref. 35381). Found in great numbers in zones of plunging waters (Ref. 27188). May be found together with Lithoxus in little forest creeks as well as in rapids (Ref. 35381).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01585 (0.00866 - 0.02902), b=3.02 (2.87 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Daya lenting (Ref. 120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
