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). Aquarium Care: In common with the Sturisoma genus it is very peaceful so you should not mix it with any fin nipping species as the long filaments to the caudal fin can be a magnet for this behavior. Provide large flat stones or roots for this species as it likes to "sprawl" out full length so needs this priority to fulfill this entitlement. A good water current and filtration is called for giving a high oxygen content in a tank that is at least 3' 0" long as this species can get quite large and needs plenty of room in an under stocked tank. Will be seen during the daylight hours. Due to the southern catchment area they would need to be kept at not too high a temperature. Sexual differences: Males can be differentiated from the females as having cheek and head bristles, with the females being that bit heavier looking. Diet: Algae, peas (without skins), cucumber and algae tablets. Breeding: Not yet known but is sure to be similar to Sturisomatichthys aureus where eggs are usually placed on the glass sides of the tank where the male guards the eggs and cleans them for up to 8 days, and when released from their egg cases will be ignored by the parents. A good first food is greens and brine shrimp.
