Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 15.9 cm SL Männchen/unbestimmt; (Ref. 36713)
Facultative air-breathing in the genus (Ref. 126274); Not so frequently occurring. Caught in rapid zones where Pseudancistrus barbatus lives although nothing is known of the ecological relationship between the two species. The odontodes on the extreme end of its snout and its pectoral spines are very well developed (Ref. 35381).
