大小 / 重量 / 年齡
成熟度: Lm ? range ? - ? cm
Max length : 12.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 37098)
背棘 (總數) : 1; 背的軟條 (總數) : 4 - 5; 臀鰭軟條: 9 - 10; 脊椎骨: 35 - 36. Differs from other species by having a wide elliptical cranial fontanel; short postcleithral process not reaching vertical through origin of dorsal fin; body coloration variable, usually with
elliptical spots along sides of body, large specimens with faint spots; or color pattern uniformly pale brown; and caudal fin with small spots or pale brown. The only other Tatia with a
variable coloration is Tatia galaxias, but this species differs from Tatia galaxias by its short postcleithral process ; its small eye, 21.4-26.3% HL and its long snout 38.8-44.3% HL. Can be further diagnosed by the following characters: nasal ossified with wide medial flanges partially sutured to lateral margin of mesethmoid and caudal-fin lobes of mature females with same length, but mature males with elongated upper lobe are other distinguishing features (Ref. 79512).
Body shape (shape guide): elongated.
Inhabits rivers (Ref. 27188). Reaches sexual maturity above 5.04 cm SL (Ref. 79512).
棲息於河。 (參考文獻 27188)
