Comments: Inhabits bare sandy bottoms in brooks and small rivers with remarkably strong current during the rainy season.  Also occurs frequently in pools and ponds with more or less stagnant water during the dry season and the period of low water (Ref. 57445).  A specimen measuring 6.5 cm SL has 80% plant matter (mainly seeds), aquatic insect larvae, detritus and sand grains in its  stomach and adjacent intestine (Ref. 57445).
