CW045 has now been described
as Corydoras colossus Tencatt, Grant, &
Bentley 2023. Similar to Corydoras
armatus but with
no spots and possesing an orange blotch to the head.Found alongside CW057.
Sometimes this species can takeon
a very dark appearance which may point to the colour
and make up of the substrate or different water parameters.
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. Diet:
Readily accepts a mixed and varied diet which includes
granular foods, tablet food, frozen bloodworm and
a good quality flake. Etymology:
The specific name colossus: derives from
the Ancient Greek KOÀOOOÓÇ (kolossós),
which means “large/giant statue”, alluding
to the relatively large, robust, armoured body of
the new species. A noun in apposition (Tencatt et
al 2023)
