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).
