Comments: Captured in creeks with rocky bottoms and in areas where the water changes level (Ref. 27188).  Lies hidden under rocks and Podostemaceae.  Its color pattern, like that of the other <i>Heptapterus</i>, provides perfect camouflage.  The species which occur more frequently with it are:  <i>Imparfinis minutus</i>, <i>Moenkhausia oligolepis</i>, <i>Pyrrhulina filamentosa</i>, <i>Characidium fasciadorsale</i> [= <i>Characidium zebra</i>] and <i>Crenicichla albopunctata</i> (Ref. 35381).
