CW146 has now been described
by Tencatt
et al. in 2022. Similar
in appearance to CW111,
but has a different colour pattern and is sympatric
with this species in the Rio Curua, Rio Xingu drainage,
Brazil. Lineage: Placed in Lineage
9, the "short-snouted" species with the
designated type species: C. punctatus. A
revision and a description 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. Sexual
Dimorphism: As well-documented in Corydoradinae
(see Nijssen, Isbrücker, 1980b; Britto, 2003;
Spadella et al., 2017), male specimens of C. thanatos
present a genital papilla, which is somewhat tubular
in shape. Aquarium male specimens eventually display
a conspicuous elongation of the first and second dorsal-fin
branched rays (Tencatt
et al). Diet:
Readily accepts a mixed and varied diet which includes
granular foods, tablet food, frozen bloodworm and
a good quality flake. Etymology:
From the Greek thánatos, which means ?death?),
the Greek god or personification of death, and the
twin brother of Hypnos, the god/personification of
sleep.
