Information:
Corydoras diphyes
belongs to the family Callichthyidae or Armoured Catfishes
from South America; namely Paraguay, and is documented
as being restricted to the tributaries of the Río
Monday, Río Acaray, the right bank tributaries
of the Río Paraná and a small stream
at Estancia María Balén. Corydoras
diphyes is also documented as being found in
Brazil. It is a recently described species of Corydoras
(2003). In its natural habitat Corydoras
diphyes usually occurs in areas which have sandy
substrates with bank vegetation entering the water.
The water in which they are found varies from dark
(stained with tannins) to clear or slightly turbid.
This particular catfish is documented as being mimicked
by Otocinclus
mimulus. Lineage:
Placed in Lineage 6. This group was always classified
under Corydoras so when a new revision is
carried out a new genus would have to be described
alongside a new type species. 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.
