The work carried out by Covain
et.al. 2016 confines the Sturisoma genera
to west of the Andes (trans-Andean), and the Sturisomatichthys
genera restricted to the east of the Andes (cis-Andean).
The first 5 thumbnail images the specimen was captured
in Feb. 2003 in the Paraná River basin in Argentina
in an area with many floating plants and larger plants
known locally as "camalotes". This species
is also well known from the La Plata River basin further
to the south. The Sturisoma genera is sometimes
not eay to identify to species as there has probably
been quite a few aquarium crossings in the past. Aquarium
Care: Happier in a aquarium with a high oxygen
content. Large planted aquarium with non aggressive
tank mates. Regular water changes must be adhered
to, to keep this animal in good health. Sexual
Differences: Mature males will grow odontodes
along the sides of the head and rostrum (snout). Diet:
Mostly vegetarian with cucumber, spinach, and algae
wafers. Meaty foods such as frozen blood worms and
live foods such as white worms and brine shrimp can
be fed sporadically. Reproduction:
As per this genus, will lay eggs usually on the tank
walls and the male will guard and fan the eggs.
La Plata River basin: Argentina, Brazil, Bolivia and
Paraguay. Type locality: Rio Paraguay.
