Last summer I found cory eggs in my tank. The eggs were eaten soon after. Unfortunately, I don't know how I got my cories to breed. Sorry.

Someone around here posted a good link to breeding cories. Try a search on MFT.

they need a wet and dry season, if i remember. you need to kinda recreate the amazon year and the changes that takes place in it, like food shortages, etc.

that site, corydora world has a great breeding article, but i can't find the site, it used to be on the top, it's a MFT sponser...

idk, mabey i am mistaken? they might be easier to breed than that.

mabey try a search for "corydora world" and you might find it.

good luck.

PlanetCatfish.com also has good information regarding cory breeding.

I have done so accidentally myself. From what I understand it is as mushroomman said, you need to recreate "seasonal changes" in your tank. What induce cories (depending upon the species that is) are rapid water temperature changes.

In the "dry" season, water temperatures are very warm and the water levels are low. During "spring" the snows on top of the mountains melt, sending a whole rush of ice water into the streams and rivers that feed the cory habitats. That "cold flood" of water can drop temperatures a whole ten degrees, and increase volumes 1000 fold.

My cories spawn primarily in the actual, seasonal spring when temperatures within my unheated tank can fluctuate as much as four or five degrees in 24hrs. When I change the water during "spring cleaning" (my yearly retrofit) I usually drain the tank to only having maybe two inches on the bottom, and then fill the tank again with relatively cool water (~66oF to 68oF). This gets cories "frisky" and within the next 48hrs I have had eggs.

Unfortunately most of the cory tankmates eat the eggs, and the one little fry that I did find this year may not have made it because I've no longer been able to locate it.

What to do to make cories spawn on purpose or to raise the fry, I've not a clue.
