he fish have lived in the same top
tank now for 2 years. In February 2005 I realised that
they were spawning. All of the fish were excited, I did
notice one pair mating whilst swimming in the middle of
the tank, they were in the usual Corydoras T-
They spawned in the late afternoon, so I did not look
for the eggs until the next morning and they are the worst
of egg eaters.
The eggs I hatch in a floating container. At 2 days old
the young are put into a rearing tank 10x10x10 inches
with 6 litres of water from the adult tank, a fine air
stone, a mature sponge filter, a small area of pea gravel
and java moss and a temperature of 76 f. (24.5°c).
I change one third of the water daily from the adult tank
and after four weeks I use aged tap water and feed twice
a day. I drop the food onto the sponge filter, they will
not not feed from the bottom of the tank.
At about two weeks I give them micro worm, at three weeks
the ones that have survived begin to show up into the
main part of the tank, I then give them brine shrimp.
At this time they also begin to feed from the bottom of
At four weeks I start feeding sera viformo tablets and
at seven to eight weeks they are put into a planted tank
to grow on.
The adults spawned on average every 7 to 10 days for almost
three months. With so few eggs found, it becomes a problem
putting the fry along with older young, they just vanish.
I do keep two tanks just for them. I reared 13 in 2005
from about 80 eggs.
This year they did not start spawning until the end of
March and the young are still just as difficult to rear.
