cory is like a Corydoras
panda look-alike, the
difference being is that C .oiapoquensis has
the caudal peduncle spot on the base of the caudal fin,
plus the tail has about 3 bands whereas C. panda
has a clear tail. Apart from that they are very much
alike, but I have found C. oiapoquensis to be
a very shy fish, hence the quick and not so great photo
here, as the fish appeared instead of waiting for it
to come nearer, you can still see the main characteristics
in the image.

The Latin name of condiscipulus actually
means schoolmate pertaining to the fact that they are
together much of the time. You can see in the imge below
the difference in the length of the snout, and of course
this shows in the different lineages of both species.

They were imported
into the U.K., as far as I know, about 1996. The
top picture is the male, I think, as the females don't
get very gravid looking or heavy before the spawning
cycle, so sometimes you can make a mistake identifying
them. I was lucky and picked up 2 males and 1 female
from a well known outlet in the north of England in
March 98 and housed them in a 17" x 15" x
15" tank. Every time that I appeared in the fishhouse
they would scatter about the tank and so I decided to
cover the top of the tank to cut down on the light.
About 1 month later,
with the tank being in darkness most of the time, I
did not notice that they had spawned, with about 12
eggs laid on the Java Moss. I had missed the first
spawning as the parents must have ate the fry, so I
took the eggs out to a separate container. The eggs
are a kind of rusty/orange colour and about 2mm in size.
There are a few
variations of this species where there is no banding
in the tail and some that have no black blotch in the

is 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 Hoplosopma (Agassiz, 1846).

Care & Compatibility
A tank setup would entail a
soft substrate such as sand or a small gravel and
a nice plant covering around the back and sides of
the aquarium. If housed in a community tank a mixture
of small South American characins or the smaller varieties
of Asian Rasboras would suffice, as larger fishes
would intimidate these shy Cory's, and would stop
them eating and would be therefore detrimental to
their overall health.
As stated above, the tank size,
but a 18" x 12" x 12" would suffice.
When they spawned the tank parameters were a temp.of
77f and a pH of 6.with a GH of 1. As mentioned before
they are apt to eating very small fry, so it is advised
to take the eggs away and introduce the fry back,
if desired, at about 1 month old. They are quite an
easy species to spawn and I was surprised that they
did when the pH was on the low side. A very shy species
and likes to hide in the tank, so give pots etc.for
The usual fare for adult
Corydoras, a good quality flake food, tablet food,
frozen bloodworm and whiteworm used sparingly.The
fry can be fed brine shrimp from a very early age
and grow quick in the first month, then they are apt
to slow down.
