a few undescribed species imported as C. reticulatus

by me with another two specimens in 2015 and as you

Corydoras reticulatus belongs to Lineage 8 sub
clade 3 along with C. sodalis and C.
latus etc. which in the future will be taken
out of the Corydoras genera and given a new
genus name. This lineage comprises of the deeper-bodied
species and also includes the Brochis which
at the present resides in the Corydoras but
will be moved back to Brochis in future literature.

near Pebas, Rio Tamya, tributary of the Rio Ucayali,
Male: 6.0cm (2¼ins)
Female: 6.5cm (2½ins)
Head, short and compact.
Body light silver-grey with
a metalic-green shimmer with black wormlike bands
forming a mosaic pattern. Darker on head and along
back. The belly region sometimes has straight black
lines in some specimens with a white background. Caudal
fin rays are banded black and white, forming six to
eight transverse rows. Dorsal fin sports a black patch
in the middle with scattered pigmentation. Small black
spots are present in the anal and adipose fins.
Care & Compatibility
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 or
in a species tank for breeding purposes. Will
do well in a community setup. Do not house with aggressive
species or large Cichlids.
As per standard Corydoras
breeding structures. Set them up with preferably more
males than females ( a ratio of 2:1 is good ) in a
18" x 12" x 12" tank with either fine
gravel or sand with either sponge filter or a corner
filter box with a good current. Install some java
moss or wool mops, this gives the females a choice
of where to place their eggs but you will probably
find that they will mostly lay them on the glass anyway.
A temperature in the mid-seventies
is good with a p.H around about the neutral (7) mark.
Feed a diet of frozen or live food such as bloodworm,
whiteworm (sparingly because of the fat content) grindleworm,
daphnia and a good quality flake or tablet food.
Make a 50% water change, when
you notice the female(s) have fattened up, with water
that is cooler so as to bring the temperature down.
A good idea is to also add a small internal filter
to push the water around the aquarium which will also
oxygenate it. If successful you can either take the
adults out and leave the eggs in the main tank or
reverse it and take the eggs out by rolling them of
the tank sides with your fingers into a small hatching
tank, you can then decide to add a anti-fungus remedy
or to leave alone. If you make the wrong choice and
the eggs fungus you will get another chance as once
Corydoras start to breed the first time they
will carry on using the afore-mentioned process.
For other tips on breeding
Corydoras go to the breeding
articles section of ScotCat where you will find plenty
of articles on the subject.
Females will get decidedly
rotund when in breeding condition with the males usually
having more pointed ventral fins.
A good quality flake food provides
all the essential vitamins that they need with extra
feedings of frozen bloodworm, white worm (sparingly)
and tablet food.
