Will corydoras breed in any circumstances?

I was wondering if I was going to have to start worrying about eggs in my 20 Gal or if my corys will even end up breeding at all. I’m not sure what I would do if they did start producing eggs so I want a reliable answer on how corydoras breed. I specifically have Peppered corys, which are a dwarf species.

 

If there is other fish in there, decent chance the eggs get ate anyway. Or when they are pretty new fry. I don't know specifics on what pH they might need to breed or what to feed to condition them for breeding.

 

I have salt and pepper cories (they are a dwarf) my ph is 7.6 ish in my 15 gallon. One of mine lay eggs almost every week. I looked it up because it usually happened a day or two after my weekly 50% water change-they usually spawn after rainfall in their natural habitats so from what I read if you feed them high protein and then do large water change with temp 2-3 degrees cooler than their water it will get them going. That being said I just leave the eggs in the tank and the gourami and adult cories eat them, I do have one fry hopping around so I put Indian almond leaves down so he can hide under that and the driftwood.

 

Generally once they're mature enough they breed fairly readily. How many have you got in there? Usually the parents or other corys (or any other fish) in the tank will eat some/most of the eggs within a few hours of them being laid or soon after they hatch. Usually if you don't do anything specific about it, you'll get the odd fry surviving every so often to boost your numbers but they won't go crazy like guppies.

I have four so far, but I was planning on getting two more, however if they are going to be breeding I might as well let them make their own spawn right?

They'll reproduce more when ready and in the mood.....my original 6 turned into 25-30 within 6 months.

Great excuse...erm....I meant reason..for another aquarium

I'd probably get a handful more anyway as they tend to bigger in larger schools/groups. They're quite a popular fish too so if they do mature and breed, you shouldn't have trouble rehoming any extras.

 

Some 'if's' here. If you have males and females, and if they are mature, and if the water is right (they like cooler water than some other corys you will end up with eggs.

If you want to trigger breeding do a large water change with water that is slightly cooler. This mimics the spring water flow that in nature triggers breeding.

 

I have Corydoras trilineatus, panda, and pygmaeus. I've never seen fry, or eggs, or and breeding behavior. I suspect it's because of my moderately hard 8.2 pH water.
