is your so-called pygmy species of Corydoras
or as I prefer to call them, a dwarf Cory, along with
is sometimes a difference in body markings in this
species, but basically they have 3 blotches running
along the body, one just under the dorsal fin, one
midway between the dorsal and the adipose fin and
a larger blotch on the caudal peduncle. Sometimes
you can get species that have these markings merging
into one band running the full length of the body
from the start of the dorsal fin to the caudal peduncle,
or even 2 bands ( see photo), but the spot/blotch
on the peduncle is always larger than the rest of
There is a very similar species, namely Corydoras
Brazil but the difference is in the body markings
where C.cochui has 4 blotches and C.habrosus,
3. In place of the large blotch in the caudal peduncle
of C.habrosus, C.cochui has 2 smaller
spots situated between the adipose fin and the caudal
peduncle (where the tail meets the body).
as you may gather now, is a small species, with
the females growing a little bit bigger than the males.
They are just too small to house in a large community
tank and will also suffer at the hands of other larger
inhabitants such as barbs, especially Tiger Barbs
who will pick on them as they sit motionless on the
substrate. An ideal tank would be a 18"x12"x12"
or a 24"x12"x12" with peaceful livebearers
such as Guppies or Platies and small characins such
You could have
the p.H. of this tank set around neutral (7.0) and
it would suit all inhabitants.Another idea of course,
and the one I prefer, is to have them in their own
tank. A 18"x12"x12" would be ideal,
with around 8 specimens, 5 males and 3 females or
6 males and 2 females. You could of course acquire
them as juveniles from other breeders and let them
grow on in this tank. A 10% water change every
week would suffice, and the best way to entice them

species with the designated type species: C.

Venezuela, in the Rio Cojedes, near El Baul, State
Male: 3.0cm (1¼ins)
Female: 3.5cm (1½ins)
Dorsal 1/7; Shape of head,
short and compact.
The ground colour of the
head and body is pale tan. Three dark blotches along
middle of body, the first below the dorsal fin,
the second between the dorsal and adipose fins and
the third and darkest is on the caudal peduncle.
The three azygous scutes before the adipose fins
have dark pigment on them. There is a scattered
dark pigment on the dorsolateral body scutes. The
ventrolateral body scutes are without dark pigment
except for the upper portions of those scutes associated
with the three dark midside blotches. Dorsal fin
has two rows of fine spots. Adipose fin with some
dark pigment on the spine. Caudal fin with four
rows of light spots in the upper lobe and three
in the bottom lobe. The remaining fins are 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 or in a species
tank due to their small size.
I set them up
( 2males and 1 female) in a 18"x10"x10"
tank with bird sand (to keep p.H.up as I have very
soft water) a sponge filter and a clump of Java Moss.
My first spawning numbered 20, ( egg size 2mm) and
as I had to go away that particular weekend the eggs
hatched when I had come back. The fry were very small
and the parents did not bother them. They grew
with a feeding of Liquifry for egglayers plus the
pickings from the sponge on the filter. They then
went on to Brine shrimp where the parents of course
would eat as well.
Smaller foods for this Corydoras
such as crushed flake, tablets, grindal worm and washed
brine shrimp. Small frozen bloodworm is also a good
