This species is found in the
middle stretches of the Rio Negro in Brazil and is
a look-alike. It has the same colouration as C.
metae from the river of the same
name in Colombia but davidsandsi has a longer
snout and the black stripe carries on into the bottom
lobe of the caudal fin while C. metae stops
short at the caudal peduncle. The C.
has melini having the same black body stripe
ending on the bottom lobe of the caudal fin, but the
stripe separates just behind the dorsal fin and continues
as two lines over the back of the body. The colouration
is also different with melini being a dirty
white with black specks to the edges of the body scutes,
while davidsandsi has a tan colouration with
no specks. Lineage: Placed in Lineage
9, the "short-snouted" species with the
designated type species: C. punctatus. A
revision in the future would constitute the resurrection
of the genus name Hoplosopma (Agassiz, 1846).
Aquarium Care: This
is akin to most of this genus, very peaceful, and
would be best housed with small to medium sized tankmates
such as Tetras, Rasboras and Danios or in a species
tank for breeding purposes. Best to purchase 6 individuals
or more as they will be happier in a group. Diet:
Readily accepts a mixed and varied diet which includes
granular foods, tablet food, frozen bloodworm and
a good quality flake.
