Etymology: Parambassis: Greek, para = near + Greek, ambassis, anabasis = climbing up (Ref. 45335).
More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical; 18°C - 25°C (Ref. 13371)
Asia: discontinuous distribution in mainland and insular southeast Asia: Chao Phraya and Mekong basins; islands of Sumatra and Borneo (Ref. 10429). Reported from the river systems of Maeklong, Peninsular and Southeast Thailand (Ref. 26336).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 30857); common length : 9.4 cm SL male/unsexed; (Ref. 10429)
Second anal spine conspicuously enlarged (Ref. 43281).
Found in main rivers and lakes (Ref. 56749). Occurs in sluggish rivers and floodplains. Grows to a fairly large size and is probably the most common species of this family, seen in the markets. Feeds on insects, crustaceans, and small fish (Ref. 12693). Used as feeds for caged fishes (Ref. 56749).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00613 - 0.03255), b=2.96 (2.77 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.58 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (14 of 100).
Nutrients (Ref. 124155
