Due to limited growing on space at the time, I eventually stopped the spawning by moving the fish into another tank which had a higher temperature, and a neutral pH, and that contained various other fish. The eggs hatched some 36 hours later, and after a further day and with their yolk sac no longer evident I moved them from the hatching trays into a small 3 gallon (UK) growing on tank, and fed the fry on a diet of liquid fry food and micro worms, after five days I stopped feeding the liquid fry food and fed the fry micro worms fine flake powder in the morning and newly hatched brine shrimp every evening, carrying out a 10% water change on the fry tank, using aged water that had the same pH and temperature of that of the fry tank, daily each morning, this continued for two weeks and as the fry were growing rapidly they were moved into a larger "growing-on" tank.

The main things that I advocate are: - Good water quality, a balanced diet, healthy fish, time and patience. Good water quality, diet, and healthy fish explain themselves, time and patience is down to the individual fishkeeper. I chose Corydoras paleatus for this study in spawning by design, not only because I had a small group already in my possession but because as I have said, I find that I can usually get these to spawn without great difficulty, although I have to say, that I used to have another group of C. paleatus many years ago that I could spawn readily, as long as it was between September and November; they simply refused to spawn in any other period, no matter what I tried - this is where time and patience comes into it. One has to be willing to wait and not expect instant success, if one thing doesn’t work try something else. If by carrying out cold water changes doesn’t happen to trigger a spawning; try altering the pH at the same time, or altering the hardness, the tap water in my area is soft, whereas in other areas, the tap water is hard, so changing the hardness may work on certain types. What apparently works for me might not necessary work for you, but remember only change one thing at a time, and be patient, give each change time to maybe take effect. But remember also that it is a hobby and no matter how good one thinks he or she is at breeding tropical fish, you won’t become a millionaire! So just enjoy your fish and delight in any successful spawning that comes along.
