orydoras reticulatus, an old favourite in the hobby, is similar
C. sodalis but this
species has no blotch in the dorsal fin and has bars instead.
There has been a few undescribed
species imported as C. reticulatus that are similar.
The species below was purchased by me with another two specimens
in 2015 and as you can see the body is somewhat deeper
with different markings.
The very similar looking
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.
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
do well in a community setup with smaller tank mates such
as Rasboras and Tetra's. Do not house with aggressive species
or large Cichlids.
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 or
in a species tank for breeding purposes.
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
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.
