Relevant Information:

Habitat: Captured in creeks with rocky bottoms and in areas where the water changes level. Lies hidden under rocks and Podostemaceae. Colouration: Its colour pattern, like that of the other Heptapterus, provides perfect camouflage. The species which occur more frequently with it are: Imparfinis minutus, Moenkhausia oligolepis, Pyrrhulina filamentosa, Characidium fasciadorsale [= Characidium zebra] and Crenicichla albopunctata. Remarks: These specimens were captured by the image contributor during his Oyapock Expedition of 2019.
