his Corydoras is usually the first
one kept by aquarists and subsequently leads them into the fantastic
world of catfishes. Many new exiting colour varieties are beginning
to appear in the hobby mostly from Venezuela and Peru, these include
the Peru Green-Stripe, the Peru Gold-Stripe
and the Peru Gold-Shoulder Red, there is also a black
variety, it may be in the future that these fish will be reclassified
into a new species, only time will tell.
In the early days of the modern hobby this
Cory along with Corydoras paleatus, the 'Peppered Cory' were
the main diet of catfish enthusiasts as there was not much call
for importing exotic species as keeping catfish was not as popular
as it is today, and with the world opening up with faster trade
routes and the growing popularity for catfish, and indeed other
exotic species, we have today hobbyists themselves who go and collect
these species and bring them back to their own tanks.
This Corydoras is abundant in the hobby mainly due to their
breeding in fish farms in the Far East and I think that this has
given us a poor representation of aenus in the aquatic shops
today. You can still find good specimens but you will have to shop
around and of course fish auctions can throw up a surprise or two.
The albino variety is also very popular with first time hobbyists.
This is probably why the serious Cory enthusiast tends to overlook
this species which has been with us for so long.
If starting off with this species buy at least half-a-dozen as with
most Cory's they are happier in their own company, and with the
comparatively low price of aeneus ( apart from the new varieties)
it would certainly not break the bank, and you could end up of course
with at least a pair of these hardy Cory's.
Breeding is comparatively easy with cool water changes
that lowers the temperature, triggering them off. Feed a good
balanced diet making sure that they get their full quota of food
if kept in a community tank. 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.
The new varieties mentioned earlier are not quite so easy to breed
and need a little more work. In the two following pictures you can
see male and female albino with the eggs laid high up on the glass
front in the full flow of an internal filter. The second photo shows
the fry against a one new pence (U.K.sterling).

Make sure that you keep them in rounded
gravel or preferably on sand as sharp gravel can erode the barbels,
making them virtually useless for breeding, especially on the
females. Even if you do keep your Cory's on rounded gravel or
sand, do keep the substrate clean as a build up of bacteria there
can also harm their delicate barbels.
As there is so many so-called varieties
of C. aeneus, it would be better to keep the them apart
in case of hybridization.
Dorsal 1/7; Anal 1/6-7; 21-23 bony scutes
in the upper lateral series, 19-21 in the lower.
Colouration uniform yellow-brown to delicate
reddish-brown with a strong metalic glint on the sides of the head
and body. Sometimes shining green, sometimes coppery or, in sunlight,
golden. The colouration along the middle of the flanks is substantially
Will do well in a community setup with smaller
tankmates such as Rasboras and Tetra's. Do not house with aggressive
species or large Cichlids.
Like to lay their eggs (300 or more) in the
direct flow of a filter usually high up on the glass where the flow
strikes. Eggs will hatch in 3 to 4 days and will use up their yolksac
after 3 days. I did find that the C. aeneus 'albino' fry
are a little more difficult to raise to adulthood, than some other
Cory's, so keep the water changes up. (See image of spawning sequel
with the eggs high on glass in the flow of internal filter and the
fry in a small plastic holding tank.)
The fry after 3 days feed on infusoria then
on to microworm, fry flake, then progress on to Brine Shrimp naupli.
Adults can be fed the usual good quality flake food, frozen bloodworm,
tablet foods, white and grindal worms.
