Etymology: Sicyopus: Greek, sika, sikya = cucumber + Greek, pous = foot (Ref. 45335).
Eponymy: Rodney Jonklaas (1925–1989) was a pioneering Sri Lankan diver, underwater photographer and zoo administrator. [...] (Ref. 128868), visit book page.

海洋; 淡水; 半鹹淡水 底中水層性; pH range: 7.0 - ? ; dH range: 5 - ?; 非產卵性溯降河的 (Ref. 51243); 深度上下限 0 - 2 m. 熱帶; 7°N - 6°N
Asia: originally known from a fast flowing stream in Atweltota, in the middle catchment of the Kalu River, Sri Lanka. Has since been collected from Sitawaka (Kelani basin) and Kuru River at Eratne (Kalu basin) and the Opatha River at Opatha (Nilwala basin).
亞洲: 在卡盧河,斯里蘭卡的中央流域中,本來在 Atweltota 已知來自一個快速的流動水流了。 自從被在 Eratne(卡盧河流域) 採集自 Sitawaka(Kelani 流域) 與 Kuru 河而且在 Opatha(Nilwala 流域) 採集自 Opatha 河以後.

Maturity: Lm ?  range ? - ? cm
Max length : 4.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 6028)
Adults are found in rocky mid-hill streams with fast flowing water. They adhere to the sides of submerged rock through sucking discs. Occur usually in water 50-150 cm deep. Carnivore. Sudden, heavy rainfall with an accompanying drop in water temperature induces spawning, usually in a cavity excavated in sand in the shelter of a stone. Eggs hatch in the event of another heavy rainfall. Larvae are swept downriver to the sea, mature adults migrate upstream to spawning grounds. Possibly amphidromous (Ref. 26364).
成魚被發現於岩石的用快速的流動水丘陵中段的溪流。 他們經過吸盤附著水下岩石的到側邊。 出現通常在水 50-150 公分深。 食肉動物。 突然又狂暴的降雨有一個水溫中陪伴下降引誘產卵, 在石頭的庇護所中通常在掘穴於沙子的一個洞。 卵在另外狂暴的降雨情況下孵化。 仔魚被清掃下游河川到海洋, 成熟的成魚移動溯河到產卵場。 可能河海兩域洄游.(參考文獻 26364)
