Do Cories eat the eggs of other fishes or their own eggs?

Hi Joahua 
Corys seldom eat their own eggs, but I do not know if they will eat the eggs of other fish.
Corys spend much of their time, after laying their eggs, in inspecting and taking care of them.

i tend to disagree... my cory's have spawned on several occasions and i myself have witnessed them eating eggs of their own and eating other cory's eggs that are spawning. so if they do lay eggs, u should either remove the eggs or the parents or you may not have many eggs left come the next day. they are most vulnurable the first 24 hours as they are still soft and easy to remove from the glass.. after the 24 hour peroid they become harder
Hi Madattiver
Please notice that I said that corys seldom eat their eggs; there are exceptions. From my reading, I understand that sometimes individual fish, or groups of fish, start eating them and in this case they should be removed after the laying is finished. This is an exception and could happen among any kind of cory.
Do not be confused by their normal behavior which could make it appear as if they are eating their eggs.
Ordinarily, when corys spawn, the breeding fishes, as well as the other corys in the tank, will spend much time checking out the eggs. They do this (or so it appears) with their mouths. Whenever they find an egg that might be going bad they eat it. This is most helpful in controling the development and spread of fungus that could destroy the eggs.

i understand from you reading they seldom eat their eggs.. another thing to consider is which species we are talking about.. most of the smaller cory's c. pygmaeus, c. hastatus and c. habrosus normally don't eat their eggs and can be left in the tank with parents..
but from my experience.. with alot of the larger cory's.. the eggs are fair game. i have watched the cory's go over the eggs.. then.. woop.. the egg is gone.. a spawn 2 times ago a female laid over 150 eggs.. after a week there were only 25 eggs left.. and these cory's usually have at least a 90% fertilization rate as they have spawned several times. i currently have 13 species of cory's and 87 cory's in total.. this is my main interest and have had alot of experience with them.. and am just talking from my experience.. as i am sure others have had differing experiences then i have.
i am not trying to start an argument over here.. just trying to say.. if you want to raise the eggs. i would recomend removing the eggs or the parents to ensure you have the best luck keeping the most eggs to try to raise. or risk the chance of them eating the eggs.
what species did you have in mind when you posted this thread joshua.. or was this just in general if they ate eggs???
what kind of cory's do you have inchworm??? always wanting to hear about other people and their cory's...

Hello again Madattivermadattiver said:
Don't worry about anyone thinking you are trying to start an argument here, Madattiver. This is only dialog and it is a good thing. After all, if we agree all of the time, how will we ever learn anything new?
I'm happy to meet someone who is interested in raising corys. They are great little fish!
I have C. aeneus (bronze and albino) 6 sterbai, 9 panda, 3 green-gold (which may be a color variation of C. aeneus--I'm not sure)1 julii and 1 melanistius. Don't ask how many C.aeneus; they won't sit still long enough for me to count heads. In addition, right now I have two tanks with very young fry.
Right after I started this post I went inside to look at them and guess what? The bronze are at it again! I had moved them into a tank with the water temperature of 82 degrees in an attempt to get them to stop spawning, but it seems the temp is down to about 76 degrees and that's all they needed.
Now, to get to the other part of your post that I quoted....... My corys' eggs hatch in between 3-4 days. If yours were still there after a week, there is a very good possibility that the eggs that were eaten were not viable anyway. What do you do to prevent fungus from developing and ruining the eggs?

ya.. slipped up on that one.. it took 2 days.. not a week for them to devour almost all the eggs... slip up on my end with all my rambling...
as for fungas prevention.. i use a few drops of meth blue added to the container containing the eggs as well as an airstone.. seems to do the trick as i have never had any eggs fungas
this is the list of cory's i presently have...
3-c. aeneus bronze + 150 fry at various stages of growth
1-c. aeneus albino
8-c. panda
7-c. trilineatus
5-c. pygmaeus
4-c. metae
6-c. schwartzi
8-c. aeneus (green lasers)
9-c. gossei
4-c. sodalis
5-c. axelrodi
5-c. oiapoquensis
10-c. hastatus
10-c. sterbai

Hi joshua
There are lots of different corydoras. Here is a link so that you can check them all out:
