    Thumbs up How do Cory Eggs actually form?


    0 Not allowed!
    I've read many articles on how Cory eggs are fertilized, laid and how they hatch. However, I couldn't find any information on how the eggs are formed inside the female to begin with. Any brief information will be appreciated.

    Well.... wikipedia has this to say about fish ovaries:

    Fish ovaries may be of three types: gymnovarian, secondary gymnovarian or cystovarian. In the first type, the oocytes are released directly into the coelomic cavity and then enter the ostium, then through the oviduct and are eliminated. Secondary gymnovarian ovaries shed ova into the coelom from which they go directly into the oviduct. In the third type, the oocytes are conveyed to the exterior through the oviduct.
    Does that help with what you wanted to know?

    Very detailed scientific explanation with too much Latin for my liking but I got the jist/gist of it, thank you very much. However, what I wanted to know is that how eggs start existing right from zero. Like, does the female fish say "hey, I'm in a pretty good mood today, I feel like making some eggs" at will? What initiates the process?

    Well corys are known to start spawning when the conditions are correct in their environment.

    In the wild this is the start of the rainy season. The water gets cooler and the chemistry alters some, which lets the fish know that the time is right for making babies.

    In aquaria, fishkeepers try to simulate this by doing a large water change with possibly slightly cooler temp replacement water.

    I believe, but I can't say with 100% certainty that the female starts producing the eggs when it senses the conditions are correct, and is not building up any sort of stockpile in the intervals between. I say this because some fish keepers report rather frequent egg laying production, and they do produce quite a few scattered eggs each time.

    Thanks again, much better than the response that Bozo gave above. So the female starts the process on her own without the help of the male and the male fertilizes the eggs once they are matured inside the female. And of course the conditions are right. Correct?

    We sometimes like to kid around on the AC and have fun, but I would be careful if I were you with the name-calling...it's unnecessary, and the mods may find it inappropriate enough to take action...just saying.

    hahaha

    bozo - sorry, made me giggle

    I'm assuming it was just in jest though.

    As for the corys, what was said about the "rainy" season has a lot to do with it. When they start getting a lot of food (live black worms seem to work great) that is the "right stuff" they begin to produce eggs, then when the colder water change happens they will scatter them.

    It has to do with ideal conditions, low stress, proper feeding and then the water change to spur corys into laying eggs
