Why wont they breed????

I have four corydoras catfish and they used to spawn every time I did a water change but they suddenly stopped. I know everything I right in the tank. All my other fish breed now but my cories. What the has happened?!?

 

Have your tried feeding them live or frozen foods? Also, when you do a water change, do you add slightly colder water?

 

I hAve given them freeze dried blood worms and when I do a water change I don't add warm water at all just cold. I'm pretty sure I have three females and a male jst wqnted to throw that in because theve given me many fry before

 

Are your females gravid? Sometimes cories will take a break from breeding and then start up again at a later date. Also if you have only one male it can be stressful for it to breed all the time and he will get tired. My males sometimes lose some scales when they breed. Feeding them some frozen bloodworms or other high protein foods can get your female ready to breed and help the male recover.
Also with your other fish the cories may be breeding and they are eating the eggs as they are being laid. Good luck.

 

What is gravid

 

I have two rally fat ones that are bigger and one is large but not nearly as fat and the other is small and skinny who I think is the male

 

Maybe you need to try some red wine, flowers, and romantic music.....;D

 

Ill have to try that......…jk

 

sometimes lowering the temps a degree or two with water changes will do the trick....other times, its just let mother nature do her thing
