Congrats! I've managed to get baby corydoras before as well, with me the trick was to spot the mother fish as after she's got the eggs fertilised she dashes about with them between two of her fins looking for somewhere to put them. I got her in the net and she put the eggs on the net, then I turned it inside out and the babies hatched in there. Very cute fish they are! Many years ago now though
We just put the breading net over the top of the eggs and trapped the little ones after they hatched. I flipped it over yesterday after one of them escaped and got eaten by a rummy.
