Comments: Most specimens were collected using  rotenone at shallow rocky reefs in the main channel of the lower Ventuari River. Water parameters taken at one site were as follows: temperature 32°C; pH 6.9; specific conductivity, 12.9 µS/cm; salinity, 0.0 ppt.; dissolved oxygen, 6.6 mg/l or 90.6% saturation. Thirteen other loricariid species have been collected syntopically with this species:  <i>Ancistrus macrophthalmus</i>, <i>Baryancistrus beggini</i>, <i>B. demantoides</i>, <i>Hemiancistrus guahiborum</i>, <i>H. subviridis</i>,  <i>Hypancistrus contradens</i>, <i>H. lunaorum</i>, <i>Hypostomus squalinus</i>, <i>Leporacanthicus galaxias</i>, <i>Pseudancistrus orinoco</i>, <i>Pseudolithoxus anthrax</i>, <i>P. tigris</i>, and <i>Spatuloricaria</i> sp.  Intestinal contents of 3 specimens examined were mostly amorphous organic detritus and inorganic sediment, although gut contents of one individual included two small snail shells (Ref. 87303).
