Etymology: Acanthocobitis: Greek, akantha = thorn + Greek, kobitis, -idos = a kind of sardine; also related with the voice Greek, kobios, Latin gobius = gudgeon (Ref. 45335); zonalternans: The specific name is derived from the Latin zonatus (girdle or a belt) and alterno, to be variegated or with two alternate colors.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 6.8 - 7.8; dH range: 8 - 18. Tropical; 24°C - 26°C (Ref. 13614)
Asia: Manipur State in India to Peninsular Thailand close to the Malay border. Collected from Brahmaputra, Chindwin, Sitang and Salween basins, and smaller streams along west coast of Peninsular Thailand, all draining to the Andaman Sea and in the Mae Khlong and Tapi basins, draining to the Gulf of Thailand. Not yet collected in the Irrawaddy, but certainly does occur there.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.8 cm SL male/unsexed; (Ref. 4832)
soft rays: 8. Distinguished from its congeners occurring in Indochinese area by an incomplete lateral line reaching at most above pelvic fin; suborbital flap present in males (Ref. 39226).
Found in a variety of streams from river mainstreams to small brooks. Seems to avoid mountain streams with steep gradient. Seems to prefer shallow riffles over small pebbles above which its marmorated color pattern makes it inconspicuous from the surface. Also collected on a muddy to sandy substrate with a few stones and numerous gastropod shells in depths ranging from 0.05 to 0.5 m.
