Maturity: Lm ? range ? - ? cm
Max length : 28.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 27732)
Has 9 branched dorsal rays; 36-40 lateral line scales; no dark spots on pelvic and anal fins (Ref. 27732); a small dark spot always present behind spiracle; sometimes tiny tubercles on side of head and large tubercles confined to snout (Ref. 12693).
有 9個分枝的背鰭鰭條; 36-40個側線鱗片; 沒有在腹鰭與臀鰭上的深色的斑點;(參考文獻 27732) 一個小的深色斑點總是出現在呼吸孔後面; 有時在頭側與大的瘤結上的極小的小瘤侷限於吻了。 (參考文獻 12693)
Occur in medium to large-sized rivers and enters flooded fields (Ref. 12975). Found on solid surfaces in flowing waters. Mostly herbivorous, feed largely on algae, periphyton and phytoplankton, but also take insect larvae or zooplankton. In current, they hold onto fixed objects with their sucker-like mouth. For breathing, water is pumped into the gill cavity through a small spiracle and across the gills for gas exchange. Large fish are sold in the markets, smaller ones are used to make prahoc (Ref. 12693). Aquarium keeping: needs plant feed; adults territorial; in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).
出現在中到大型的河而且進入被水淹沒的田野。 (參考文獻 12975) 在流動的水域中棲息於純粹水面了。 大部份食草, 主要食物為藻類，固著生物與浮游植物,但也吃昆蟲幼生或浮游動物。 在水流中，他們附著在固定的目標上面用吸盤狀的嘴巴。 對於呼吸，水經過一個小的呼吸孔被灌入鰓腔與越過鰓達成氣體交換。 大的魚在市場被賣, 較小的一些被用來製造 prahoc 。 (參考文獻 12693) 水族館保持: 需要廠吃; 成魚領域性; 形成 5個或更多個體的群體; 水族館最小體型 60 公分.(參考文獻 51539)
