Description:
Measurements and counts in the Table 2. Member of
H. fowleri group. Body dorsoventrally depressed
and elongated, widest at cleithrum. Dorsal profile
of body straight and gently ascending from tip of
snout to anterior region of orbit, and horizontally
straight from this point to dorsal-fin origin and
gently descending to end of caudal peduncle. Ventral
profile of body straight from tip of snout to origin
of anal fin and gently ascending from this point to
caudal peduncle. (Oyakawa et al 2018). Habitat:
known only from above the two great falls of Rio Curuá,
a tributary of Rio Iriri, in the area of Serra do
Cachimbo. Collections made bellow the two falls of
Rio Curuá have failed in capture the species,
suggesting that the new species might be restricted
to the portion of the river above the two great falls.
(Oyakawa et al 2018). Aquarium Care:
Not the easiest genera to keep as they will need clean,
oxygen rich water and a strong current. Does not do
well in imports due to its difficulty in traveling
containers. Sexual Differences: Males
tend to have odontodes (hair like structures) on the
first ray of the pectoral fins and the head in males
is broader. Diet: Grazes on microscopic
algae, mostly diatoms and green algae growing on rugged
and light-coloured rocks, and submersed vegetation.
Chironomid and simuliid larvae, as well as tiny crustaceans,
are recorded in its diet. When scraping algae off
the substrate, the fish makes vigorous mouth movements
and jerky movements, probably related to its mouth
making alternate grazing and attaching to the substrate.
In the aquarium feed dry foods, algae wafers, Spirulina
and normal tablet foods. Frozen foods, Artemia
nauplii, glass worms and Daphnia. Etymology:
The specific name, villasboas, is a patronym that
honours the Orlando, Claudio and Leonardo Villas Boas
brothers, three frontiersmen that led the Expedição
Roncador-Xingu during the years of 1943 to 1949, with
the mission to explore a wide and unknown territory
of the Amazonian regions of Brazil. In 1949, the expedition
reached the tablelands of the Serra do Cachimbo. One
of the most important results of this expedition was
the establishment of the Parque Indígena do
Xingu in 1961, the first huge indigenous area in all
South America. The area of the park is 26.420 km2
in the northern of Mato Grosso State and nowadays
protects 14 indigenous ethnicities. A noun in apposition.
