Corydoras has been around since, as far as
my investigations go, 1982. It was first captioned
in the Tropical Fish Hobbyist magazine in that year
by Dr.Burgess as possibly Corydoras bicolor,
and later on in 1990 in David Sands Catfishes of the
World volume 1, as a colour variation of Corydoras
delphax. To add further to the mystery you can
also see this fish in Werner Seus's Corydoras book
as C004 ( the numbers given out by the German publication,
DATZ, to unidentified Cory's), but it is in this book
that a further caption explains the new name and the
author. It was
named Corydoras virginiae by Dr.Warren E.Burgess
in 1993 in honour of Adolfo Schwartz's wife, Virginia.

as Corydoras zangama a trade name
given to them in the UK around that period, they reside
in my 6' 0" community tank in my lounge with
large cats (Syno's, Chrysichthys
etc.) and a few large characins. They have been very
hardy and can compete no problem at all with the other
occupants for food.
mentioned this is quite a hardy Cory and will do fine
in a community tank. Would be best to purchase a group
of 4-6 or even more as they do like their own company.

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.

of dorsal down to gill covers. Gill-covers have
a yellow/orange glimmer. All fins clear.
Care & Compatibility
This is akin to most of this
genus, very peaceful, and would be best housed with
small to medium tankmates such as Tetras, Rasboras
and Danios but will do
well with larger species or in their own tank for
from Larry Vires: I received a group of 6 fish
ranging in size from 1.5-2.0" SL April of 1997.
The fish did not have any noticeable dimorphism, but
were fed very heavily on blackworms and tablet foods
for the next 3 months. Water quality was maintained
at a pH of 7.0 and Total Dissolved Solids were approximately
150 ppm. Along with weekly water changes, the fish,
3 after shipping losses, all grew to a maximum size
of 2" rather quickly and one of the fish became
rather plump. However, there was no spawning activity
noticed. I then decided
to use a trick which I had used with other wild-caught
Corydoras. It is not highly scientific, but
is effective. Water changes of approximately 25% are
done daily with reverse osmosis water which is about
15' F cooler than the tank water, which should be
around 82' F. This will usually have an affect after
about a week, but these fish are very stubborn and
did not spawn until 3 weeks had gone by. There
were only about 25 eggs from each spawning, but the
fry were large for Corydoras, and grew to 3/4"
in their first month. Brine shrimp nauplii were fed
for the first 2 months, and blackworms were added
to the diet after the first month. Flake foods should
also be supplemented into their diet 3-4 times a week
to ensure a well rounded diet.
The usual fare for adult
Corydoras, a good quality flake food, tablet food,
frozen bloodworm and whiteworm used sparingly.
