Occurs mainly in stagnant waters, creeks and river shorelines, over soft bottoms. On the Atlantic versant it lives between 0 and 500 m of elevation, but in the northern Pacific sector is found between 10 and 45 m in the Tempisque and Bebedero drainages; in the Río Tárcoles drainage, where it was probably introduced, it lives between 670 and 1220 m elevation. Inhabits shallow waters with mud or litter substrata in temperatures of 20 to 37°C. Feeds on ooze, detritus, diatoms and occasionally on filamentous algae and aquatic insects (Ref. 36880).
主要生活在污濁的水域, 小溪與河海岸線, 在軟質底部之上。 在大西洋的山斜坡上，它住在海拔的 0 與 500 公尺之間, 但是在北太平洋地區中被發現在 Tempisque 與 Bebedero 流域的 10 與 45 公尺之間; 在 Rio Tarcoles 流域, 在那裡它可能被引入, 它住在 670 與 1220 公尺海拔之間。 棲息於淺水域在 20 到 37個 ° C. 的溫度有泥或胎窩下層土壤 吃軟泥，碎屑，矽藻與偶然地吃絲狀的藻類與水生昆蟲.(參考文獻 36880)
