well, yes it's that easy ... or no it's not. there are some folks who breed corydoras and don't even try very hard. there are others who try very hard but never succeed. is there some luck involved? i'd say yes but more than that is patience. don't expect it to happen in a week, or a month ... or even a year. the corys have to be sexually mature and that depends on the species. that might take two years. they have to be well conditioned and that depends on how well you take care of them.they would breed? Is it really that easy?
