Which Snails For A Fry Tank?

[Plecc]

Hi all,
 
Which snails would be best for a corydoras grow-out tank?
 
I think, I read somewhere that a certain snail if fed the correct veggies, actually produces a food source for the very small fry!
 
Please, nothing that reproduces like crazy.

I have never heard of a snail doing that but can't say I've looked for that sort of info

 
A single nerite perhaps?

 But why are you wanting a snail for the tank?

I'm looking for something to use as a clean-up crew to consume any uneaten food and if i'm lucky take out a bit of algae.
 
I have assassin snails in another tank, would they be suitable?

They'll be replacing uneaten food with poo though, which you'd still need to clean, right?
 
I'm not sure if assassins would be right as they need more protein than algae.
