Biologi     Ordlista (t.ex. epibenthic)

Often found in creeks, but sometimes captured in rivers, specially during the dry season. A formidable predator; it consumes essentially aquatic insects, fish and plant material. Not very popular among aquarists because of its aggressive behavior (Ref. 27188).
