would explain that they were out of stock.
Fortunately his firm sometimes cooperates
with a German importer, and in September
2006 Miloš called to inform me that
through the German importer he had
gotten a shipment of 50 wild specimens, of
which 36 were alive. The price was high,
but I was too near my goal to turn back;
I hopped into my car and drove to the
wholesaler at once.
They turned out to be adult fish and not
in very good condition. I don’t like buying
wild adult fish, since they could be 3 years
old or 15. They can also be difficult to
acclimate to life in captivity. Also, what if
someone in Peru is breeding the species
and shipping the spent breeders? These
and other questions were tormenting me,
but I produced a big chunk of cash for 10
specimens—I just couldn’t let someone
else take home my dream cories!

Success at Last
On the way home my holy grails
punctured the double plastic bag with
their spines, and they arrived with only a
small amount of water left, but they were
still alive. They were quite thin, and two
died during the first week, but the other
eight were adapting well. I fed them well
with daphnia, red worms, white worms,
and tubifex, and within a few weeks they
had filled out and I dared to hope for a
For the first few months the fish were not
very active, but at the end of December they
showed more energy and began swimming
up and down the aquarium walls. They
were especially active every afternoon.
This continued for more than a month with
no further spawning behavior. At times it
looked as if they would spawn any minute,
but nothing. I was frustrated and tried
all the tricks—water changes, lowering
the temperature, raising the temperature,
feeding more live foods, artificial rain—all
to no avail.
I asked my friends on the Internet forum
Petfrd.com what to do. The next day I had
a reply from Paul Dixon from the Bolton
Aquarium: “They need tons of Java moss
in the spawning tank.”
I arranged a spawning setup according
to Paul’s advice, and a day later my fish
spawned! It started in the late afternoon.
The fish lost all their shyness and colored
up nicely. The males began to chase the
females, and they assumed the typical
Corydoras “T” position, after which the
