There are reputed to be different
forms of this species in the hobby.
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 Hoplisoma (Agassiz, 1846). As
of the latest revision (Dias
et al 2024) Corydoras atropersonatus
has now been placed in Lineage 9 and has the new genus
name of Hoplisoma and also
a change to the specific name to atropersonatum.
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:
Feeding is not a problem as they will readily consume
commercial foods such as flake, granular and tablet
foods and frozen foods such as bloodworms and daphnia,
like all fish they benefit from regular feedings of
live foods such as Daphnia, Cyclops, Grindal worms
and bloodworms. Etymology: The specific
name atropersonatum: from the Latin atropersonatum
= 'with a black mask' alluding to the mask across
the eye. Remarks:
This species is
still found on some online sources as Corydoras
atropersonatus.
