Etymology: Hexanematichthys: Greek, exa = six + Greek, nema = fialement + Greek, ichthys = fish (Ref. 45335).
More on author: Hamilton.

Marine; brackish; demersal; amphidromous (Ref. 51243); tropical.

Indo-West Pacific: Pakistan, west and east coast of India, Bangladesh, Myanmar, Thailand, Malaysia, Singapore, Indo-Australian Archipelago (but not occurring in Papua New Guinea or Australia). Also reported from China, and Philippines (Ref. 7050). Reports from eastern Africa and the Red Sea need confirmation.

Max length: 45.0 cm TL male/unsexed (Ref. 7050); common length: 30.0 cm TL male/unsexed (Ref. 3290).

Found along the coastline, mainly around estuaries. Ascends into fresh water of the upper tidal zone. Occurs in the Mekong delta (Ref. 12693). Feeds on invertebrates and small fishes. An important food fish (Ref. 3290). Marketed fresh (Ref. 12693).

Preferred temperature (Ref. 123201): 26.5 - 29.3, mean 28.6 °C (based on 2316 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00490 (0.00250 - 0.00959), b=3.13 (2.96 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.6 se; Based on food items.

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

Fishing vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).

Price category (Ref. 80766): Medium; Very questionable: based on ex-vessel price for species in this family.
