Collected syntopically with S. minutum in some localities. Stomachs of eleven specimens were analyzed where 6 had immature aquatic Diptera (Chironomidae), Oligochaeta, unidentified plant fragments and sand. A study showed that the diet of immature individuals was composed of Chironomidae and Ephemeroptera. Individuals larger than 3.5 cm SL are reported to be capable of spawning and thus are considered adults (Ref. 122319). Ferrer, J. and L.R.
