If your nitrate is 0 then either something is wrong with your tank or you weren't honest with your test results like you said...
 
Apple snails get to be as large as a human fist. I doubt a frontosa would be able to fit one in its mouth.
 
Well, there's an apple snail species that can get to the size of a baseball. Like all apple snails, it lays eggs above the waterline, so they'd have a better chance of multiplying than most inverts. The only problem is, like with any large snail, a death will quickly pollute the water. They eat, algae, but when it comes to your plants, they only prune off the dead parts.

Another option would be the Maylaysian snail, which stays tiny, but also stays out of danger. These guys are a helpful substrate-dweller that will come up at night. Sort of an aquatic equivalent of earthworms. They're hard to buy, though. Typically, if you have them, great (so long as you don't keep spiny eels, but that's another story...) and if you don't, you don't. Interesting fact: Because of their shell structue, they're the only snails that can cohabitate with loaches.
 
I am not sure an adult marbled cray could defend itself from an adult frontosa. Mine don't get more than about 4 inches and they are not very aggressive. As far as getting them to reproduce, all you have to do is wait until they are adults. I keep mine in a busy community tank and some of the young still manage to surivive. I had one in a tank by itself with some bristlenose and I couldn't believe how many offspring she had, lol. I will have to say that the adults are very attractive in my opinion and they also come in blue which is very pretty.
