How long will corys bellies be swollen before they lay eggs?
How long will corys bellies be swollen before they lay eggs? half of my corys appear to have much bigger bellies than the others and I am hoping this means they are getting some eggs to lay. Can anyone confirm this? and how long will they have big bellies for beofre they lay eggs?

Most fish don't have a "gestation period" in that they spawn after a certain amount of time, but follow environmental triggers instead. That means that your cories could be gravid pretty much indefinitely until they think it is the right time to spawn.

+1 to the above. Also - the big bellies thing generally just means they're female. I have six peppered cories and two of them are definitely female as they are bigger and fatter than all the others. I have no idea when they are about to spawn, they do so about once a month I think.
