; 淡水 底中水層性. 熱帶
Asia: southeastern Thailand in provinces Trat, Chantaburi, Chonburi and on Koh Chang island; apparently restricted to small coastal streams (Ref. 39226), but may possibly be found all along the mountain range, including the Mekong basin (Ref. 12693).
亞洲: 在德樂府，尖竹汶府中的泰國東南部, 春武裏府與在象島上; 顯然地侷限於小的海岸溪流 (參考文獻 39226)了, 可能地但是可能被發現於所有沿著山範圍, 包括湄公河流域.(參考文獻 12693)
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 7.5 cm SL 雄魚/尚未辨別雌雄; (Ref. 12693)
背的軟條 (總數) : 12; 臀鰭軟條: 8. Consists of 10-12 dark bars usually vertically split; 8+8 branched caudal rays; 8 1/2 branched dorsal rays; males with a suborbital flap and absence of median notch in lower jaw (Ref. 39226). Lateral line complete or incomplete, at least reaching to tips of pelvic fins; caudal fin with 5-7 very irregular rows of spots on rays; scales lacking between pectoral fins, but present on back (Ref. 12693).
由 10-12 組成深色的橫帶通常垂直地分離; 8+8 分枝了尾部的鰭條; 81/2個分枝的背鰭鰭條; 雄性有一個眶下的鰓蓋而且在下頜中缺乏中央的凹槽。 (參考文獻 39226) 側線完整或不完全的, 至少延伸到腹鰭頂端; 在鰭條上尾鰭有 5-7 非常不規則的列斑點; 鱗片缺乏在胸鰭之間, 但是位於背面之上.(參考文獻 12693)
Inhabit small, shallow, high gradient streams with gravel and boulder substrates in forests. Diet probably consists of insect larvae and some algae, as seen in other nemacheilines (Ref. 12693). A female 5.24 cm SL contains ovulae about 0.7 mm diameter (Ref. 39226).
在森林中棲息於小的﹐水淺的﹐和高落差的溪流有礫石與磐石的地方底部。 食物可能由昆蟲幼生與一些藻類組成, 如在其他的 nemacheilines 中見到的.(參考文獻 12693) 一條母魚 5.24 公分 SL 含有大約 0.7 mm 直徑的卵。 (參考文獻 39226)
