Maturity: L_m ? range ? - ? cm
Max length : 17.5 cm TL jantan/; (Ref. 79585); Berat maksimum terpublikasi: 91.60 g (Ref. 79585); Umur maksimum dilaporkan: 18 Tahun (Ref. 72479)

Inhabits large free flowing clear rivers, small streams, drainage ditches and artificial ponds and impoundments (Ref. 11225). Feeds on zooplankton, detritus, higher plants and sometimes on the scales of fish. Gametogenesis takes place during the dry season in time for reproduction to begin during the rainy season (Ref. 12225). Reproduction could be carried out in captivity (Ref. 27188).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01549 (0.01234 - 0.01944), b=3.07 (3.03 - 3.11), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 2.4 ±0.1 se; based on diet studies.

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

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