duri punggung lunak (Keseluruhan (total)) : 4; Sirip dubur lunak: 56 - 63; vertebrata, bertulang belakang: 48 - 52. Ompok argestes differs from its Indian and Sri Lankan congeners by the combination of the following characters: body color pattern mottled; predorsal profile uniformly convex; maxillary barbels reach or extend slightly beyond the base of the dorsal fin; eye diameter 14.2-17.1% head length; body depth at anus 19.8-22.3% standard length (SL); head width 14.3-16.8% SL; caudal peduncle depth 5.6-6.5% SL; and vertebrae 48-52 (Ref. 116164).

Found among submerged roots and marginal vegetation in slow-flowing, shaded regions of rivers and streams with a substratum of mud or leaf debris (Ref. 116164).

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=0.00562 (0.00279 - 0.01132), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

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).
