you know, the cory and platty idea is very possible. I have a guppy and cory 55G. My guppies breed like crazy (just like platties) and i sell some occasionally. Cories breed pretty easily too, some species, like your 2 cories, what i'm saying is that you can have a tank full of cories and platties, for a very little cost, they just need your time and patience (to raise them)
That is a very good point. If you can get the right combo of male and female Bronze C. Aeneus, feed them well and have the right water conditions, they will breed like crazy. Once they start the usually spawn every 3-4 weeks. However, rasing the fry is a lot more complicated then rasing the fry of live bearers because they grow a lot slower and are more sensitive to water conditions. So its not a good idea to raise cory fry with platty fry.
As for the Peppered Cories, Ive heard they arent that hard to breed either, they just eat their eggs very quickly. They also eat the eggs of other cory species, so you might have a problem there.
