Colour pattern in this species
can be variable. It can also be mistaken for Brochis
ambiacus. Juveniles
can often show large spots on body which reduce in
size as they mature. Lineage: Placed
in Lineage 8 sub clade 4 which comprises the "intermediate
long-snouts" with deeper bodies. It also includes
Brochis in sub-clade 1 which was synonymised
with Corydoras by Britto in 2003 but in time
there will be a revision which will resurrect Brochis
Cope, 1871 to full genera again.
As of the latest update Corydoras agassizii
has now been placed in Lineage 8 sub clade 4 and has
the new genus name of Brochis (2024).
Aquarium Care: This is akin to most
of this genus, very peaceful, and would be best housed
with small to medium tank mates such as Tetras, Rasboras
and Danios or in a species tank for breeding purposes.
Diet: A good quality flake food and
tablet food for adults with sporadic feedings of frozen
or live food will keep your Corydoras/Brochis
in good health. Etymology: The specific
name agassizii: in honour of Jean Louis Agassiz,
the zoologist, born in Switzerland, (1807-1873). Remarks:
Still found on some online sources as Corydoras
agassizii.
