Lives on the bottom and feeds on mollusks, crustaceans, and organic debris. Frequently occurs on sandy bottoms. Often escapes into the sediment where it hides among the anfractuosities of the submerged stocks (Ref. 35381). A juvenile in a stream of the rio Araguaia was recorded to clean the piscivorous characin Hoplias cf. malabaricus (Ref. 50806).
