Relevant Information:

The work carried out by Covain et.al. 2015 confines the Sturisoma genera to east of the Andes (cis-Andean), and the Sturisomatichthys genera restricted to the west of the Andes (trans-Andean). S. nigrirostrum's natural habitat is described as mostly soft water backwaters in which there are no water plants although the banks are overgrown with Pistia or Eichornia. Branches extending below the surface and driftwood on the bottom serve as surfaces that the fish can scour for aufwuchs and this fish can actually scrape off some of the wood itself as an aid in digestion. One of the more easier Sturisoma species to identify due to its short slightly turned up black snout. Aquarium Care: Good filtration and not to be crowded in the tank as Nitrate levels should be kept low. Sexual Differences:Can be sexed out by the male having bristles on the cheeks. Diet: Vegetarian with Lettuce, algae (real or tablets/wafers) sweet potatoes, cuccumber and mashed peas.
