Robust body gray with bluish highlights, deep and almost rhomboid. Males with very long gonopodium that reaches the base of the tail; together with the young, with 6 - 8 dark bars (diffused in females) (Ref. 36880).

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).
主要生活在污浊的水域, 小溪与河海岸线, 在软质底部之上。 在大西洋的山斜坡上，它住在海拔的 0 与 500 公尺之间, 但是在北太平洋地区中被发现在 Tempisque 与 Bebedero 流域的 10 与 45 公尺之间; 在 Rio Tarcoles 流域, 在哪里它可能被引入, 它住在 670 与 1220 公尺海拔之间。 栖息于浅水域在 20 到 37个 ° C. 的温度有泥或胎窝下层土壤 吃软泥，碎屑，硅藻与偶然地吃丝状的藻类与水生昆虫.(参考文献 36880)
