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- position.

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 the tank.

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.
